a neurological disorder is any disorder of the nervous system is usually due to cell loss. the ultimate goal of cns therapy is to replace lost cells and tissue. there is no neuroprotective, pharmacological and effective treatment available that restores the injury-induced loss of function. recent studies suggest that identification of adult neural stem/progenitor cells indwelling in the neuroge...

context stem cells have the potential to generate a renewable source of cells for regenerative medicine due to their ability to self-renew and differentiate to various functional cell types of the adult organism. the extracellular microenvironment plays a pivotal role in controlling stem cell fate responses. therefore, identification of appropriate environmental stimuli that supports cellular p...

Neurodegenerative diseases are the hereditary and sporadic diseases which are characterized by progressive neuronal loss of the nervous system and are emerging as the leading cause of death, disabilities, and a socioeconomic burden due to an increase in life expectancy. There are many neurodegenerative diseases including Alzheimer’s disease, Parkinson’s, disease, amyotrophic lateral...

Articular cartilage, the load-bearing tissue of the joint, has limited repair and regeneration ability. The scarcity of treatment modalities for large chondral defects has motivated researchers to engineer cartilage tissue constructs that can meet the functional demands of this tissue in vivo. Cartilage tissue engineering requires 3 components: cells, scaffold, and environment. ...

purpose: to report the outcomes of conjunctival-limbal autograft (clau) in patients with unilateral total limbal stem cell deficiency (lscd) emphasizing surgical problems, complications, and their management. methods: in this prospective interventional case series, clau combined with amniotic membrane transplantation as a graft was performed on 26 patients with unilateral total lscd due to chem...

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 ...

background:   objective: this study presents an economical and simple co-culture system for pluripotent stem cells generation from neonatal mouse testis   materials and methods: isolated testicular cells were cultured in dmem/f12. characteristics of the isolated cells and obtained es-like cell were immune-cytochemically confirmed by examining the presence of plzf, vimentin, oct4 and nanog prote...

the identification of multipotential mesenchymal stem cells (mscs) derived from adult human tissues such as bone marrow and connective tissues has provided exciting prospects for cell-based tissue engineering and regeneration. this review article focuses on the biology of mscs, their differentiation potentials in vitro and in vivo, and their application in tissue engineering. our current unders...
