Genetically Engineered Mouse Embryonic Stem Cell – derived Cardiomyocytes as a Suitable Model on Drugs Toxicity In vitro

Background DOX is a powerful chemotherapeutic agent used in the treatment of solid tumors and malignant hematological diseases. However, its cardiac toxicity limits the clinical usefulness of this drug. Previous reports have shown Corticosteroids induce a cytoprotective effect on cardiomyocytes. Mouse transgenic embryonic stem cell-derived pure cardiomyocytes may be considered as a model for a...

P-92: Retinoic Acid and STO Co-Culture System Enhance Mouse Embryonic Stem Cell

Spermatogonia stem cells: A new pluripotent source for repairment in regenerative medicine

Recently new reports have proved the pluripotency of spermatogonial stem cells (SSCs) derived from male gonad. This pluripotent stem cells resembled Embryonic stem cells recognized as Embryonic Stem like cells (ES like cells). ES like cells forms sharp edge colonies that are immunopositive to pluripotency markers and have differentiation capacity to Ectodermal, Mesodermal and Endodermal layers....

Cell based therapies in retinal diseases

Background Degenerative retinal diseases, including age related macular degeneration, glaucoma, and hereditary retinal dystrophies are major causes of blindness. The principal defect in these diseases is cell loss which is amenable to both cell based neuroprotective and neuroregenerative therapies. To briefly review the lines of research and potential candidates for cell based therapies among ...

Effects of Treatment with Bone Morphogenetic Protein 4 and Co-culture on Expression of Piwil2 Gene in Mouse Differentiated Embryonic Stem Cells

Background Specific growth factors and feeder layers seem to have important roles in in vitro embryonic stem cells (ESCs) differentiation. In this study,the effects of bone morphogenetic protein 4 (BMP4) and mouse embryonic fibroblasts (MEFs) co-culture system on germ cell differentiation from mouse ESCs were studied. MaterialsAndMethods Cell suspension was prepared from one-day-old embryoid bo...

The Validated Embryionic Stem Cell Test to Predict Embryotoxicityinvitro

Backgrounds: A straight-forward way to identify whether a drug or environmental chemical can be harmful to unborn baby is to evaluate its effect on laboratory animals. All invivo methods need large number of animal and are therefore time consuming and expensive. However, the thousands of chemicals in need of testing, to reduce the spending of live animals, an assortment of in vitro assays has ...
