Objective: Since mesenchymal stem cells (MSC) can differentiate into bone, cementum, and periodontal ligament, they can be used to treat aggressiveperiodontitis. The limited number of MSCs requires replenishment of growth factor in the cell culture process. Since growth factor is quite expensive,an alternative material is needed. Mauli banana stem has antioxidant and immunomodulatory properties. Methanol extract of Mauli banana stem isknown to be toxic toward MSCs; therefore, another solvent with a non-toxic effect is needed, such as a water solvent. We analyzed the toxicity of Maulibanana stem water extract on MSC in vitro.Methods: In this laboratory experimental (true experimental) study with a Post-test Only Control Group Design, MSC cultures were treated withMauli banana stem water extract at 10, 20, 40, 60, 80, and 100 mg/mL dosages. One group without any treatment served as a control group and onewas a media control group. Each group was incubated for 24 h and then was given 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromidereagent and analyzed by an enzyme-linked immunosorbent assay (ELISA) reader.Results: One-way analysis of variance showed a significant difference.Conclusion: Mauli banana stem water extracts at 10, 20, 40, and 60 mg/mL were not toxic toward MSC in vitro, while dosages of 80 and 100 mg/mLdosage were toxic.

Background: Regenerative therapy has been progressing into the utilization of mesenchymal stem cell (MSC). Nevertheless, the limited number of MSC has put growth factor as an essential supplement for cell culture media yet relatively unaffordable because highly priced. Alternative compound which cost reasonably is required. Exogenous phytochemical material in herbal plant extract may increase the number of MSC, one of which is mauli banana stem. Purpose: To analyze secondary metabolites identified in mauli banana stem water extract. Method: Mauli banana stem was macerated using water solvent to be analyzed qualitatively for alkaloid, tannin, flavonoid, saponin, terpenoid, diterpen and steroid. Screening was followed by quantitative analysis to determine the total of alkaloid, flavonoid, condensed tannin and hydrolysable tannin. Result: Secondary metabolite compounds of mauli banana stem water extract were alkaloid (4.15%), hydrolysable tannin (1.055%), condensed tannin (0.42%) and flavonoid (0.31%). Conclusion: Mauli banana stem water extract has potential as alternative growth factor to increase the number of MSC in vitro.

In this study, we explored the effect of the water extract of Cinnamomum osmophloeum Kanehira (COK) leaves on hair growth by in vitro and in vivo assays. Using an in vitro 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay, it was found that the proliferation of rat vibrissae and human hair dermal papilla cells (hDPCs) was significantly enhanced by the COK leaf extract treatment. As determined by quantitative real-time polymerase chain reaction (RT-PCR), the messenger RNA (mRNA) levels of some hair growth–related factors including vascular endothelial growth factor, keratinocyte growth factor (KGF), and transforming growth factor-β2 were found to be higher in the cultured hDPCs exposed to COK leaf extract than those in the untreated control group. In the hair-depilated C57BL/6 mouse model, the stimulation of hair growth was demonstrated in the group of COK leaf extract treatment. Both photographical and histological observations revealed the promotion of the anagen phase in the hair growth cycle by the COK leaf extract in the C57BL/6 mice. Finally, the ultra performance liquid chromatography (UPLC) showed that the COK extract contained mostly cinnamic aldehyde and a small amount of cinnamic acid. The results suggest that the COK leaf extract may find use for the treatment of hair loss.

T-2 toxin and its metabolite HT-2 toxin are one of the most toxic mycotoxins of type A-trichothecenes, which are produced mainly by Fusarium species. Therefore, study of Fusarium toxins T-2 toxin and HT-2 toxin is an essential issue because they could also play role in failures of reproductive functions as well as endocrine system of domestic animals. Assessment of the effect of A-trichothecene mycotoxin HT-2 toxin alone or combined with insulin-like growth factor (IGF-I), leptin and ghrelin on estradiol secretion by rabbit ovarian fragments in vitro was done. Rabbit ovarian fragments were incubated without (control group) or with HT-2 toxin, or its combinations with IGF-I, leptin and ghrelin at various concentrations for 24 h. Secretion of 17β-estradiol was determined by ELISA. Firstly, HT-2 toxin at the doses 10 and 100 ng.ml-1, but not at 1 ng.ml-1 decreased 17β-estradiol secretion by ovarian fragments. Secondly, 17β-estradiol secretion was not affected by HT-2 toxin exposure combined with growth factor IGF-I, metabolic hormones leptin and ghrelin. In conclusion, HT-2 toxin has potent direct dose-dependent effects on ovarian steroidogenesis in rabbits. These direct effects of HT-2 mycotoxin on ovarian steroidogenesis could impact negatively on the reproductive performance of rabbits.

Background: High fat diets are known to cause a positive fat balance and consequently to the accumulation of adipose mass, this diet does not seem to stimulate fat oxidation in the same way in obese and lean subjects. HFD was an inducing factor for ICAM-1 expression in the aorta of Wistar rats. HFD effect on ICAM-1 seems to be time dependent. ICAM-1 is one of the first events in the formation of atherosclerotic lesions. HFD up-regulated Cav-1, regulated expression other biomarker in HFD is eNOS. Recent studies showed that E. longifolia Jack protected HFD animal model from atherosclerosis based on the reduce atherosclerotic plaque size and formation HFD-rats treated with E. longifolia Jack.Objective: To prove that Eurycoma longifolia has anti inflammatory effect on endothelial cell blood vessels of Sprague Dawley rat with high fat diet.Method: Study design was experimental study, by used Randomized Post Test only Control Group Design with Kruskal-Wallis test was used to analyze the differences among groups and followed by a Mann Whitney test. Treatment is ethanolic or water extract of Eurycoma longifolia Jack, and out come are sICAM-1 and eNOS levels. Thirty Sprague Dawley (SD) Rat, were divided into 6 groups. C(-) was SD group, C(+) was group with HFD, X1 (SD treated with EL dosage 10 mg/kg), X2 (SD treated with EL dosage 15 mg/kg), X3 (HFD treated with EL dosage 10 mg/kg), X4 (HFD treated with EL dosage 15 mg/kg).

Introduction<br />Liver fibrosis (LF) results from the unregulated chronic wound healing process in liver tissue. Transforming growth factor-beta (TGF-β) is the major contributing cytokine of LF promotion through activation of quiescent hepatic stellate cells (HSCs) into myofibroblasts (MFs) and increased extracellular matrix (ECM) deposition such as collagen leading to scar tissue development. Mesenchymal stem cells (MSCs) have an immunomodulatory capability that could be used as a new treatment for repairing and regenerating LF through suppression of TGF-β. This study aimed to examine the role of MSCs in liver fibrosis animal models through suppression of TGF-β levels without scar formation particularly in the proliferation phase.<br /><br />Methods<br />In this study, a completely randomized design was used with sample size of 24. Male Sprague Dawley rats were injected intraperitoneally (IP) with carbon tetrachloride (CCl4), twice weekly, for eight weeks to induce LF. Rats were randomly assigned to four groups: negative control, CCl4 group, and CCL4 + MSC-treated groups T1 and T2, at doses of 1 x 106 and 2x106 cells, respectively. TGF-β levels were analyzed by enzyme-linked immunosorbent assay (ELISA). One-way ANOVA and a least significant difference (LSD) was used to analyse the data. <br /><br />Results<br />The TGF levels of LF rat models decreased on day 7 after MSC administration. The levels of TGF-β in both MSC groups T1 and T2 decreased significantly compared with the control group (p&lt;0.05). The TGF-β suppression capability of T2 was optimal and more significant than that of T1.<br /><br />Conclusion<br />MSCs can suppress TGF levels in liver fibrosis induced rats.

Abstract The oocyte quality acquired during in vitro maturation (IVM) are the main limitative factors affecting the embryo production. The aim of the present research was to study effects of fibroblast growth factor 2 (FGF2) and insulin-like growth factor 1 (IGF1) during IVM of bovine oocytes on their developmental potential after parthenogenetic activation. Bovine cumulus-oocyte complexes (COC; n = 1176) were cultured for 22h in either standard maturation medium (TCM-199 supplemented with 10% fetal calf serum (FCS), 0.2 mM sodium pyruvate, 10 μg/ml FSH and 10 μg/ml LH; Control) or maturation medium supplemented with different concentrations (5–160 ng/ml) of FGF2 and IGF1. After IVM, matured oocytes activated by sequential treatment with ionomycin followed by DMAP and cyclohexamide and then cultured up to the blastocyst stage. The obtained blastocysts were fixed, and the total cell number and the level of apoptosis were determined using DAPI and TUNEL staining. The data from 4 replicates (77–91 oocytes per treatment) were analyzed by ANOVA. Cleavage rates of activated oocytes did not differ between groups and ranged from 63.7 to 68.1%. The addition of 10, 20 and 40 ng/ml of FGF2 to the IVM medium led to an increase in the yield of blastocysts [from 19.6±1.8% (Control) to 35.2±3.4, 29.8±1.9 and 31.1±2.1%, respectively (P&lt;0.05)] and in the total cell number in embryos that developed to the blastocyst stage (P&lt;0.05). Meanwhile, the blastocyst yield and the total cell number in blastocysts in the IGF1-treated groups were similar to that in the control group. No effects of both growth factors on the proportion of apoptotic nuclei in blastocysts (5.3–7.1%) were observed. Thus, FGF2 (but not IGF1) are able to maintain competence for parthenogenetic development of bovine COC during their maturation invitro.

Abstract The evaluation of factors responsible for the protection of the oocytes attained the metaphase-II stage from aging is importance for successful in vitro embryo reproduction. The aim of the present research was to study dose-dependent effects of epidermal growth factor (EGF) and prolactin (PRL) on the quality of bovine oocytes after their aging in vitro. Bovine cumulus-enclosed oocytes (CEOs) were matured in vitro for 20 h in TCM 199 containing 0.2 mM sodium pyruvate, 10% fetal calf serum (FCS), 10 μg/ml FSH and LH. At the end of in vitro maturation, oocytes were transferred to TCM 199 supplemented with 10% FCS (aging medium) and cultured for additional 24 h in the absence (Control) and in presence of EGF (10 and 50 ng/ml) and PRL (20 and 50 ng/ml). After prolonged culture oocytes were used for apoptosis detection (TUNEL staining, n=251) and the state of chromosomes evaluation (Tarkowski’s cytogenetic method, n=359). The data from 3–4 replicates were analyzed by ANOVA. At the end of prolonged culture (24 h) the rate of apoptotic oocytes in the Control group was 47.4±8.5%. EGF at concentration of 10 ng/ml and PRL at both doses decreased this rate to 15.0–22.1% (p &lt; 0.05). Furthermore, PRL (not EGF) reduced the frequency of abnormal chromosome modifications (decondensation, adherence, clumping) at concentrations of 20–50 ng/ml from 58.7±2.1% (Control) to 41.2±1.9 and 45.6±2.7% respectively (p &lt; 0.01). Thus, EGF and PRL is able to maintain the apoptosis resistance of bovine oocytes during their prolonged in vitro culture as well as PRL have the decelerating effect on abnormal modifications of M-II chromosomes. The research was supported by RFBR (17-29-08035) and the Ministry of Science and Higher Education of Russia.

Intravenous Xuebijing (XBJ) therapy suppresses paraquat (PQ)-induced pulmonary fibrosis. However, the mechanism underlying this suppression remains unknown. This work aimed to analyze the miR-140-5p-induced effects of XBJ injection on PQ-induced pulmonary fibrosis in mice. The mice were arbitrarily assigned to four groups. The model group was administered with PQ only. The PQ treatment group was administered with PQ and XBJ. The control group was administered with saline only. The control treatment group was administered with XBJ only. The miR-140-5p and miR-140-5p knockout animal models were overexpressed. The gene expression levels of miR-140-5p, transglutaminase-2 (TG2), β-catenin, Wnt-1, connective tissue growth factor (CTGF), mothers against decapentaplegic homolog (Smad), and transforming growth factor-β1 (TGF-β1) in the lungs were assayed with quantitative reverse transcription polymerase chain reaction (qRT-PCR) and Western blot analysis. The levels of TGF-β1, CTGF, and matrix metalloproteinase-9 (MMP-9) in the bronchoalveolar lavage fluid were assessed by enzyme-linked immunosorbent assay (ELISA). Hydroxyproline (Hyp) levels and pulmonary fibrosis were also scored. After 14 days of PQ induction of pulmonary fibrosis, AdCMV-miR-140-5p, and XBJ upregulated miR-140-5p expression; blocked the expressions of TG2, Wnt-1, and β-catenin; and decreased p-Smad2, p-Smad3, CTGF, MMP-9, and TGF-β1 expressions. In addition, Hyp and pulmonary fibrosis scores in XBJ-treated mice decreased. Histological results confirmed that PQ-induced pulmonary fibrosis in XBJ-treated lungs was attenuated. TG2 expression and the Wnt-1/β-catenin signaling pathway were suppressed by the elevated levels of miR-140-5p expression. This inhibition was pivotal in the protective effect of XBJ against PQ-induced pulmonary fibrosis. Thus, XBJ efficiently alleviated PQ-induced pulmonary fibrosis in mice.
