BACKGROUND Intravitreal injection of human mesenchymal stem cells has been shown to be effective in slowing the progression of diabetic retinopathy in an animal model of chemically induced diabetes mellitus. We studied changes in growth factor levels released from human mesenchymal stem cells in the vitreous cavity as well as changes in growth factor levels in host retinal neurons following int...

BACKGROUND In regenerative medicine, use of each of the mesenchymal stem cells derived from bone marrow, cord blood, and adipose tissue, has several cons and pros. Mesenchymal stem cells derived from cord blood have been considered the best source for precursor transplantation. Direct reprogramming of a somatic cell into induced pluripotent stem cells by over-expression of 6 transcription facto...

Background: In recent decade, human umbilical cord blood derived mesenchymal stem cells (hUCB-MSCs) provide enormous potential for appropriate cell therapy, but they have limited growth potential and cease to proliferate due to cellular senescence, so providing a strategy for increasing the stem cell survival is necessary.  Methods: In this investigation, MSCs characterized by flow cytome...

Objective Adult stem cells which are derived from different tissues, with their unique abilities to self-renew and differentiate into various phenotypes have the potential for cell therapy and tissue engineering. Human adipose tissue is an appropriate source of mesenchymal stem cells with wide differentiation potential for tissue engineering research. In this study isolated stem cells from hum...

Tissue engineering skeletal muscle in vitro is of great importance for the production of tissue-like constructs for treating tissue loss due to traumatic injury or surgery. However, it is essential to find new sources of cells for muscle engineering as efficient in vitro expansion and culture of primary myoblasts are problematic. Mesenchymal stem cells may be a promising source of myogenic prog...

background  isolation of adipose tissue mesenchymal stem cells (mscs) with current enzymatic methods has some limitations. for example, it is costly and time-consuming and results in a heterogeneous cell population that making compromise proliferation and differentiation of mscs. also, it is accompanied with the increased risk of culture contaminations because of several handling steps.in this ...

Human endometrium contains mesenchymal stem cells (eMSC) which have the ability to differentiate into three cell lineages and the potential in therapeutic applications. We hypothesize that using environmental induction in culture media such as dexamethasone, human recombinant insulin and human epidermal growth factor (hEGF) can differentiate endometrial stem cells into myoblast. These agents ha...
