tendon never restores the complete biological and mechanical properties after healing. bone marrow and recently adipose tissue have been used as the sources of mesenchymal stem cells, which have been proven to enhance tendon healing. stromal vascular fraction (svf), derived from adipose tissue by an enzymatic digestion, represents an alternative source of multipotent cells, which undergo differ...
Background Theca cells play important roles during folliculogenesis. They synthesize androgens, provide crosstalk with granulosa cells and oocytes during development, and provide structural support of the growing follicle to produce a mature and fertilizable oocyte. In children patients who are going to be ovariectomy, follicogenesis is at early stage and thus the follicles need to be mature in...
Spinal cord injury (SCI) is a debilitating disease which leads to progressive functional damages. Because of limited axonal regeneration in the central nervous system, there is no or little recovery expected in the patients. Different cellular and molecular approaches were investigated in SCI animal models. Cellular transplantation of stem cells can potentially replace damaged tissue and provid...
Background and purpose: Properties of biocompatibility and biodegradation are important factors in choosing a polymer to prepare nano-fiber for medical and biological purposes. PLGA high attention in tissue engineering for the above properties, the aim of present study is the evaluation of rat bone marrow stromal cells cultured on PLGA nanofibers. Material and methods: In this study, the PL...
Background and Objective: Mobilization of Hematopoietic Stem Cells (HSCs) for transplantation and the importance of -adrenergic signals in induction of this process have been well investigated. However, little is known about the role of -adrenergic signals in mobilization of HSCs and factors influenced by these signals. The Chemokine Stromal Derived Factor -1 (SDF-1) which is expressed by hum...
background: acute appendicitis with appendicial endometriosis is a very infrequently encountered condition during pregnancy. decidualization is the hypertrophy of endometrial stromal cells by the effect of progesterone. similarly, in pregnancy, ectopic stromal endometrial cells in endometriosis can also be transformed by the same mechanism and ectopic decidua (deciduosis) may occur case: here...
The tumor microenvironment (TME) is a complex environment composed of variety stromal cells and immune that infiltrate the space. Recent clinical work has shown intratumoral cell infiltration.
objective: tendon never returns to its complete biological and mechanical properties after repair. bone marrow and, recently, adipose tissue have been used as sources of mesenchymal stem cells which have been proven to enhance tendon healing. in the present study, we compared the effects of allotransplantation of bone marrow derived mesenchymal stromal cells (bmscs) and adipose derived stromal ...
