Mesenchymal stem cells derived from Wharton's jelly of the human umbilical cord (hUC-MSCs) possess various advantageous properties, similar to bone marrow-derived mesenchymal stem cells (BM-MSCs), including self-renewal, extended proliferation potential and multilineage differentiation potential. In this study, we hoped to determine whether hUC-MSCs could(More)
Aged epidermal cells have the capacity to dedifferentiate into stem cell-like cells. However, the signals that regulate the dedifferentiation of aged epidermal cells remain unclear. Here, we provide evidence that Wnt/β-catenin is critical for aged epidermal cell dedifferentiation in vivo and in vitro. Some aged epidermal cells in human ultrathin epidermal(More)
Mesenchymal stem cells (MSCs) have been optimal targets in the development of cell based therapies, but their limited availability and high death rate after transplantation remains a concern in clinical applications. This study describes novel effects of platelet rich clot releasate (PRCR) on rat bone marrow-derived MSCs (BM-MSCs), with the former driving a(More)
BACKGROUND Bone-marrow-derived mesenchymal stem cells (BM-MSCs) can contribute to wound healing after skin injury. However, the role of BM-MSCs on repairing skin appendages in renewal tissues is incompletely explored. Moreover, most preclinical studies suggest that the therapeutic effects afforded by BM-MSCs transplantation are short-lived and relatively(More)
Excessive systemic inflammation following burns could lead to acute kidney injury (AKI). Mesenchymal stromal cells (MSCs) suppress immune cell responses and have beneficial effects in various inflammatory-related immune disorders. However, autologous MSCs are not vital enough for the treatment because of the severely burned patients' deleterious condition.(More)
Increasing attention is being placed on the use of adult stem cells due to their potential therapeutic applications for unmet medical needs. Among all adult stem cell types, umbilical cord mesenchymal stem cells (UCMSCs) can be collected easily and does not harm newborns and the mothers. The excellent pluripotency and proliferation potential of UCMSCs has(More)
It has been reported that Wnt/β-catenin is critical for dedifferentiation of differentiated epidermal cells. Cyclin D1 (CCND1) is a β-catenin target gene. In this study, we provide evidence that overexpression of CCND1 induces reprogramming of epidermal cells into stem cell-like cells. After introducing CCND1 gene into differentiated epidermal cells, we(More)
BACKGROUND Sweat glands (SGs) can not regenerate after complete destruction in the severe skin injury, so it is important to find a ideal stem cell source in order to regenerate functional SGs. Hair follicle stem cells (HFSCs) possess the obvious properties of the adult stem cells, which are multipotent and easily accessible. In this research, we attempted(More)
Recent studies showed that mesenchymal stem cell (MSC) transplantation significantly alleviated tissue fibrosis; however, little is known about the efficacy on attenuating cutaneous scar formation. In this study, we established a dermal fibrosis model induced by bleomycin and evaluated the benefit of bone marrow-derived mesenchymal stem cells (BM-MSCs) on(More)
BACKGROUND Esophageal squamous cell carcinoma is one of the most common malignancies in the world. Studies have confirmed that there are many genes abnormally hypermethylated in esophageal squamous cell carcinoma. The objective is to detect methylation of the RASSF1A gene promoter and the expression of the DNA methyltransferase 1 (DNMT1) protein in(More)
