Novel Therapeutic Strategies

Interstitial lung disease, a term for a group of disorders, causes lung fibrosis, is mostly refractory to treatments and has a high death rate. After diagnosis the survival is up to 3 years but in some cases the patients live much longer. It involves a heterogenous group of lung diseases that exhibit progressive and irreversible destruction of the lung due to the formation of scars. This results in lung malfunction, disruption of gas exchange, and eventual death because of respiratory failure. The etiology of lung fibrosis is mostly unknown with a few exceptions. The major characteristics of the disease are comprised of injury of epithelial type II cells, increased apoptosis, chronic inflammation, monocytic and lymphocytic infiltration, accumulation of myofibroblasts, and inability to repair damaged tissue properly. These events result in abnormal collagen deposition and scarring. The inflammation process is mild, and the disease is primarily fibrotic driven. Immunosuppressants do not treat the disease but the evidence is evolving that both innate and acquired immune responses a well as the cytokines contribute to at least early progression of the disease. Furthermore, mediators of inflammation including cytokines are involved throughout the process of lung fibrosis. The diverse clinical outcome of the disease is due to different pattern of inflammatory markers. Nonetheless, the development of novel therapeutic strategies requires better understanding of the role of the immune response. This review highlights the role of the immune response in interstitial lung disease and considers the therapeutic strategies based on these observations. For this review several literature data sources were used to assess the role of the immune response in interstitial lung disease and to evaluate the possible therapeutic strategies for the disease.

AbstractStem cell-based therapy is a new therapeutic option that can be used in patients with cardiac diseases caused by myocardial injury. Cardiac magnetic resonance imaging (MRI) is a new noninvasive imaging method with an increasingly widespread indication. The aim of this review was to evaluate the role of cardiac MRI in patients with myocardial infarction undergoing stem cell therapy. We studied the role of MRI in the assessment of myocardial viability, stem cell tracking, assessment of cell survival rate, and monitoring of the long-term effects of stem cell therapy. Based on the current knowledge in this field, this noninvasive, in vivo cardiac imaging technique has a large indication in this group of patients and plays an important role in all stages of stem cell therapy, from the indication to the long-term follow-up of patients.

Cell Based Therapy

Regenerative cell based therapy has potential to become effective adjuvant treatment for patients with atherosclerotic disease. Although data from animal studies support this notion, clinical studies undertaken in patients with acute and chronic coronary artery disease do not conclusively demonstrate benefits of such therapy. There are many questions on the stem cell translational roadmap. The basic mechanisms of stem cell-dependent tissue regeneration are not well understood. There is a debate regarding characterization of specific cell types conferring therapeutic effects. In particular, the role of endothelial progenitor cells as a specific reparative cell subtype is questioned, and the role of myeloid cell linage in fostering of vasculo- and angiogenesis is being increasingly appreciated. Intense discussions surround the place of stem/progenitor cells in atherosclerosis progression, plaque destabilization and vessel remodeling. This paper summarizes the current knowledge on the regenerative stem/progenitor cell definitions, mechanisms of stem cell trafficking, homing and their involvement in atherosclerosis progression.

No single animal model can reproduce all of the human features of both acute and chronic lung diseases. However, the rabbit is a reliable model and clinically relevant facsimile of human disease. The similarities between rabbits and humans in terms of airway anatomy and responses to inflammatory mediators highlight the value of this species in the investigation of lung disease pathophysiology and in the development of therapeutic agents. The inflammatory responses shown by the rabbit model, especially in the case of asthma, are comparable with those that occur in humans. The allergic rabbit model has been used extensively in drug screening tests, and this model and humans appear to be sensitive to similar drugs. In addition, recent studies have shown that the rabbit serves as a good platform for cell delivery for the purpose of stem-cell-based therapy.

Background: Human endometrium with consecutive regeneration capability undergoes monthly hormonal changes for probable implantation, which confirms the presence of the cells in the basalis layer known as stem cell. Objective: Previously, we reported the isolation and culture of the mesenchymal-like cells from human endometrium. In this study, we evaluated the biological and stemness characteristics of these cells. Materials and Methods: The characterization of Yazd human endometrialderived mesenchymal stem/stromal cells (YhEnMSCs) was assessed using immunofluorescence (IF) staining for CD105, VIMENTIN, and FIBRONECTIN as markers and RT-PCR for CD166, CD10, CD105, VIMENTIN, FIBRONECTIN, MHCI, CD14, and MHCII genes. Flow cytometry (FACS) was performed for CD44, CD73, CD90, and CD105 markers. Moreover, the differentiation capacity of the YhEnMSCs to the osteoblast and adipocytes was confirmed by Alizarin Red and Oil Red staining. Results: YhEnMSCs expressed CD105, VIMENTIN, FIBRONECTIN, CD44, CD73, and CD90 markers and CD166, CD10, CD105, VIMENTIN, FIBRONECTIN, and MHCI, but, did not express CD14, MHCII. Conclusion: Our data confirm previous reports by other groups indicating the application of endometrial cells as an available source of MSCs with self-renewal and differentiation capacity. Accordingly, YhEnMSCs can be used as a suitable source for cell-based therapies.

Background: Stroke is a major challenge in neurology due to its multifactorial genesis and irreversible consequences. Processes of endogenous post-stroke neurogenesis, although insufficient, may indicate possible direction of future therapy. Multiple research considers stem-cell-based approaches in order to maximize neuroregeneration and minimize post-stroke deficits. Objective: Aim of this study is to review current literature considering post-stroke stem-cell- based therapy and possibilities of inducing neuroregeneration after brain vascular damage. Methods: Papers included in this article were obtained from PubMed and MEDLINE databases. The following medical subject headings (MeSH) were used: “stem cell therapy”, “post-stroke neurogenesis”, “stem-cells stroke”, “stroke neurogenesis”, “stroke stem cells”, “stroke”, “cell therapy”, “neuroregeneration”, “neurogenesis”, “stem-cell human”, “cell therapy in human”. Ultimate inclusion was made after manual review of the obtained reference list. Results: Attempts of stimulating neuroregeneration after stroke found in current literature include supporting endogenous neurogenesis, different routes of exogenous stem cells supplying and extracellular vesicles used as a method of particle transport. Conclusion: Although further research in this field is required, post stroke brain recovery supported by exogenous stem cells seems to be promising future therapy revolutionizing modern neurology.

Self Renewal

Abstract The self-renewal, survival and differentiation of hematopoietic stem cells (HSC) are greatly influenced by the activities of neighboring osteoblasts and non-osteogenic bone marrow (BM) stromal cells such as fibroblasts, endothelial cells and adipocytes. Previously, we showed that osteoblasts from human long bones support the in vitro self-renewal as well as myeloid differentiation of human CD34+ cord blood cells. Recently, Li’s and Scadden’s groups provided in vivo evidence indicating a primary role of trabecular osteoblasts as a major component of HSC niche and of stromal osteoblastic cells in facilitating the self-renewal of HSCs. We have now asked whether osteoblasts contribute to early lymphopoiesis as well as myelopoiesis, by measuring the cellular outpout of purified HSCs on isolated osteoblasts alone, or with added non-osteoblast stromal cytokines as well. We prepared mature osteoblasts, as monitored and confirmed by homogeneous OPN and CD61 expression, by pretreating osteoblastic cells isolated from neonatal calvaria of C57BL/6 mice (CD45.2) with 1X10−7 M PTH. Purified OB were then co-cultured for 6 days with Lin− BM cells (CD45.1+) isolated from congenic B6 mice(CD45.1) and labeled with CFSE. Osteoblast coculture stimulated the proliferation of Lin− CD45.1+ BM cells 50-fold during culture, with most cells (87%) remaining tightly adherent to the osteoblast monolayer; no live cells were recovered from Lin− BM cell culture without osteoblasts. In addition to mature granulocytes/monocytes, a substantial amount of CD45.1+B220+ B lymphocytes (about 10% of small size cells gated by forward and side scatter), were detected. In contrast, very few CD45.1+Lin-Sca-1+c-Kit+ (LSK) cells or CD45.1+Lin−Sca-1−c-Kit+ (CMP) cells were detected under these conditions. Most B220+ cells attached to osteoblasts were found to be CD43+CD24+ pre-B cells undergoing division. In contrast to the cells recovered attached to the osteoblasts, the pre-B lymphocytes found in suspension were more mature with phenotype of B220+CD43−CD24+. Prevention of direct contact of Lin− BM cells with osteoblasts by Transwell co-culture abrogated the production of pre-B cells in both adherent and suspension compartments, indicating that physical contact is required for the interaction. Interestingly, when 20ng/ml of SCF, 6ng/ml of IL-3, 10ng/ml of IL-6 and 25ng/ml TPO were added to osteoblast/Lin− cell co-culture, B lymphpoiesis was repressed, while the production of CD45.1+LSK HSCs and CMPs was significantly enhanced. These data demonstrate a direct role of osteoblasts in inducing and supporting the early development of B lymphocytes from HSCs or/and common lymphoid progenitors. Additional cytokines, perhaps provided in specific in vivo niches by non-osteogenic stromal cells, cooperate with the stimulatory signals from osteoblasts to promote the survival and expansion of HSCs. Taken together, these results suggest that osteoblasts may be the mammalian analog of the avian Bursa of Fabricius, and that their local degree of proximity to non-osteogenic stromal cells may define specific microniches for stem cell survival, myelopoiesis and/or B lymphopoiesis.
