Bone marrow stem cells participate in tissue repair processes and may have roles in skin wound repair. Diabetes is characterized by delayed and poor wound healing, and type 1 diabetes seems to lead to stem cell dysfunction. Hence, stem cell dysfunction could contribute to poor healing, and stem cell-based therapies may be efficacious in diabetic wounds. We investigated the potential of exogenou...
The RNA binding protein YBX1 is a key regulator of epidermal progenitor cell senescence that prevents the mRNA translation critical senescence-associated secretory phenotypes (SASP) transcripts such as CXCL1 and IL8. Decreased levels during aging enables production SASP-related proteins subsequent induction senescence. Posttranslational modifications YBX1, phosphorylation at Ser 102, can modify...
In the last 15 years, there has been a significant increase in the number of researchers interested in studying Mesenchymal Stem Cells (MSCs). MSCs are self-renewing, heterogenic, and multipotent cells that have multi-lineage potential to differentiate not only in to cell types of mesodermal origin but also other various cell lineage MSCs migrate to inflammatory tissues and apply immunosuppress...
Arsenic is a carcinogen with transplacental activity that can affect human skin stem cell population dynamics in vitro by blocking exit into differentiation pathways. Keratinocyte stem cells (KSC) are probably a key target in skin carcinogenesis. Thus, we tested the effects of fetal arsenic exposure in Tg.AC mice, a strain sensitive to skin carcinogenesis via activation of the v-Ha-ras transgen...
Perception of the adipose tissue has changed dramatically over the last few decades. Identification of adipose-derived stem cells (ASCs) ultimately transformed paradigm of this tissue from a passive energy depot into a promising stem cell source with properties of self-renewal and multipotential differentiation. As compared to bone marrow-derived stem cells (BMSCs), ASCs are more easily accessi...
One of the major objectives of tissue engineering is to reconstitute skin from stem cells. This requires multipotent skin stem cells and the ability to guide these cells to form a piece of skin with proper architecture and skin appendages. Based on previous progress, we develop a simplified procedure that can be useful for large-scale screening of factors that can modulate the hair formation ab...
In the interfollicular epidermis stem cells (KSC) generate transit amplifying (TA) that, after symmetric divisions, produce differentiating daughters. We isolated and characterized highly proliferative epidermal basal cell population “early” TA (ETA) cells, based on its capacity to adhere type IV collagen. Proliferation colony forming efficiency in ETA are lower than KSC, but higher “late” (LTA...
The objective of this study was to demonstrate that stem cells isolated from discarded skin obtained after debridement can be used with collagen and fibrin-based scaffolds to develop a tissue-engineered vascularized dermal equivalent. Discarded tissue samples were collected from severely burned patients undergoing wound debridement. Stem cells were isolated from the adipose tissue layer and the...
multiple sclerosis (ms) is an autoimmune inflammatory demyelinating disease of the central nervous system. the aim of this study was to investigate the neuroprotective effects of transplanted human umbilical cord blood mesenchymal stromal cells (ucb-msc) derived neural progenitor cell (mdnpc) in eae, an experimental model of ms. to initiate neuronal differentiation of ucb-mscs, the pre-inductio...
