BACKGROUND: Mesenchymal stromal cells are multipotent cells considered to be of great promise for use in regenerative medicine. However, the cell dose may be a critical factor in many clinical conditions and the yield resulting from the ex vivo expansion of mesenchymal stromal cells derived from bone marrow may be insufficient. Thus, alternative sources of mesenchymal stromal cells need to be explored.CONTENT: There are multiple extra-embryonic tissues emerging during gestation including umbilical cord blood (UCB), amniotic fluid (AF), Wharton’s jelly, the amniotic membrane and the placenta, which are all discarded following birth. Fetal stem cells from these sources actually represent a new class of stem cells developmentally and operationally located between the state of embryonic stem cells and adult stem cells, sharing and exhibiting features of pluripotency and multipotency, without necessarily implying that they can generate every type of tissue.SUMMARY: Fetal stem cells have been recently isolated from several tissues (amniotic fluid, umbilical cord, Wharton’s jelly, amnion and placenta). They are derived either from the fetus proper or from the supportive extra-embryonic structures. They represent ideal sources for regenerative medicine since they are easily accessible, exhibit high proliferation rates, do not form teratomas and present no ethical reservations like embryonic stem cells (ESC). Their functional features indicate that they actually represent intermediates between ESC and adult stem cells.KEYWORDS: mesenchymal stem cells, fetal stem cells, amniotic fluid, umbilical cord, placenta, wharton’s jelly

Mesenchymal stem cells (MSCs) have been derived from multiple sources of the horse including umbilical cord blood (UCB) and amnion. This work aimed to identify and characterize stem cells from equine amniotic fluid (AF), CB and Wharton's Jelly (WJ). Samples were obtained from 13 mares at labour. AF and CB cells were isolated by centrifugation, while WJ was prepared by incubating with an enzymatic solution for 2 h. All cell lines were cultured in DMEM/TCM199 plus fetal bovine serum. Fibroblast-like cells were observed in 7/10 (70%) AF, 6/8 (75%) CB and 8/12 (66.7%) WJ samples. Statistically significant differences were found between cell-doubling times (DTs): cells isolated from WJ expanded more rapidly (2.0±0.6 days) than those isolated from CB (2.6±1.3 days) and AF (2.3±1.0 days) (P<0.05). Positive von Kossa and Alizarin Red S staining confirmed osteogenesis. Alcian Blue staining of matrix glycosaminoglycans illustrated chondrogenesis and positive Oil Red O lipid droplets staining suggested adipogenesis. All cell lines isolated were positive for CD90, CD44, CD105; and negative for CD34, CD14 and CD45. These findings suggest that equine MSCs from AF, UCB and WJ appeared to be a readily obtainable and highly proliferative cell lines from a uninvasive source that may represent a good model system for stem cell biology and cellular therapy applications in horses. However, to assess their use as an allogenic cell source, further studies are needed for evaluating the expression of markers related to cell immunogenicity.
