Osteoarthritis (OA) is the most common degenerative joint disorder worldwide. OA represents an increasing threat to the quality of life of affected persons as well as for health resources expenditure. The incapability of cartilage to heal has been long time regarded as the major cause of progressive joint degeneration and functional impairment. Recent reports about the presence of progenitor cell populations within adult Read More

Consisting of seed cells and scaffold, regenerative medicine provides a new way for the repair and regeneration of tissue and organ. Collagen/hydroxyapatite (HA) biocomposite scaffold is highlighted due to its advantageous features of two major components of bone matrix: collagen and HA. The aim of this study is to investigate the effect of internal structure of collagen/HA scaffold on the fate of rat mesench Read More

Bone marrow-derived mesenchymal stem cells hold great potential for cytotherapeutics of neurodegenerative disorders, including Parkinson’s disease. The neurotrophic factor neurturin can rescue dopaminergic neurons damaged during the disease process. Lmx1α can promote mesencephalic dopaminergic differentiation during embryogenesis. In this study, we tested a cytotherapeutic strategy combining NTN/L Read More

Administration of mesenchymal stem cells (MSCs) that have a reliable potential for chondrogenic differentiation is a promising approach currently employed to treat articular cartilage lesions (focal defects and osteoarthritis) in patients as a mean to enhance the poor intrinsic capabilities of this specialized tissue for self-repair. However, there is still a critical need for improved designs, as reproduction of a native structural and fu Read More

Our goal was to address if intermittent hypobaric hypoxia (IHH) exposure can help to increase the number of peripheral blood circulating progenitor cells and side population (SP) stem cells, in order to establish the usefulness of this intervention for skeletal muscle repair, because these cells play a role in tissue regeneration. Male Sprague-Dawley rats were studied in two basal states: untrained and trained and com Read More

Oral squamous cell carcinoma (OSCC) is amongst the most prevalent form of cancer worldwide with its predominance in the Indian subcontinent due to its etiological behavioral pattern of tobacco consumption. Late diagnosis, low therapeutic response and aggressive metastasis are the foremost confounders accountable for the poor 5 year survival rate of OSCC. These failures are attributed to the existence of “Cancer S Read More

Induced pluripotent stem (iPS) cells were created from mouse fibroblasts by induced expression of Yamanaka factors, Oct3/4, Sox2, Klf4, and c-Myc. This technique has quickly resulted in an exponential increase in the amount of pluripotency studies, and has provided a valuable tool in regenerative medicine. At the same time, many methodologies to generate iPS cells have been reported, and are comprised mainly of v Read More

Alternative splicing (AS) generates multiple mature mRNAs from a single pre-mRNA, so AS is the main contributor for the diversity of the proteins, participating in most of the cellular processes. For pluripotent stem cells (PSCs), great effort has been made to search for pluripotency-related genes and their regulatory mechanisms. However, the sophisticated regulation still remains to be clear. Recent studies indicate that ste Read More

Aims: A systematic review and meta-analysis were performed to explore the clinical outcome of the transplantation of stem cells from various human tissue sources in cirrhotic patients. Methods: The relevant papers were searched via PubMed, EMBASE, and Cochrane Library databases. Changes in liver function before and after stem cell therapy were evaluated (self-control data). Difference in liver function and incidence Read More

Tumoral angiogenesis is mainly an endothelial cell-mediated process, which has been largely demonstrated to take on a crucial role in tumor growth, invasion, and metastasis. Thus, tumor-associated neovasculature represents a pivotal target in cancer therapy. Several mechanisms take part in the genesis of this pathological vasculature, most notably neoangiogenesis and postnatal vasculogenesis. These processes may a Read More
