Rabbits have the capacity to regenerate holes in their ears by forming a blastema, a tissue that is made up of a group of undifferentiated cells. The purpose of the present study was to isolate and characterize blastema progenitor cells and compare them with marrow mesenchymal stem cells (MSCs). Five New Zealand white male rabbits were used in the present study. A 2-mm hole was created in the a...
according to significant improvements in the tissue engineering field over the past several years, lung tissue cells have recently attracted more attention due to the high prevalence and diversity in related diseases. however, selection of an appropriate cell type, screening of suitable conditions for growth and proliferation, as well as subsequent implantation into the body to repair and regen...
Objective- To investigate and compare growth potential as well as aging of mesenchymal stem cells (MSCs) derived from rat bone marrow tissue and adipose tissue (AT) occurred at epicardial and epididymal regions. Design- Experimental study. Animals- 10 Wistar Rats. Procedures- Rat MSCs occurred at bone marrow and epicardial and epididymal AT were isolated and culture expanded through sev...
OBJECTIVE Regeneration of the insulin-secreting beta-cells is a fundamental research goal that could benefit patients with either type 1 or type 2 diabetes. beta-Cell proliferation can be acutely stimulated by a variety of stimuli in young rodents. However, it is unknown whether this adaptive beta-cell regeneration capacity is retained into old age. RESEARCH DESIGN AND METHODS We assessed ada...
مقدمه: یکی از شایعترین اختلالات ریوی در بزرگسالان بیماری های انسدادی مزمن ریه (copd) است که شامل برونشیت مزمن و آمفیزم می باشد. شدت این اختلال در تعیین میزان پاسخ به درمان موثر است و لذا امروزه سعی می شود معیارهای مختلفی در جهت درجه بندی شدت بیماری copd استفاده شود که از جمله آنها می توان به معیارهای بالینی ارائه شده توسط american thoracic society (ats) اشاره نمود. شناسایی ارتباطات موجود بین ای...
Objective: In this study, it was aimed to make in vitro characterization of the formulations by preparing hydrogel using chitosan, a biocompatible and natural polymer, PVP, synthetic polymer. addition, effects hydrogels containing FGF on proliferation keratinocyte cells were investigated. Methods: Within scope with different properties prepared their water absorption capacity, viscosities exami...
Summary The neocortex, the seat of our higher cognitive abilities, has expanded in size during evolution certain mammals such as primates, including humans. This expansion occurs development and is linked to proliferative capacity neural stem progenitor cells (NPCs) neocortex. A number cell-intrinsic cell-extrinsic factors have been implicated increasing NPC capacity. However, metaboli...
Normal human bone marrow stromal cells (BMSC) were isolated from Dexter-type long-term cultures according to their capacity to adhere to plastic and to their lack of hematopoietic antigens. The BMSC displayed a homogeneous appearance and a myofibroblastic phenotype in culture. The stromal cells (SC) were shown to support the proliferation of purified CD34+ hematopoietic progenitors and permitte...
in this syudy a continuous bovine kidney cell line derived from a primary bovine kidney cells was established for the first time in iran. the cells were originating from two-day-old normal male calf of holstein breed. the cell cultures were continuously passaged following complete proliferation of primary cells. the specific properties or characteristics of the cell were defined using cytogene...
objective(s): throughout evolution, mammalians have increasingly lost their ability to regenerate structures however rabbits are exceptional since they develop a blastema in their ear wound for regeneration purposes. blastema consists of a group of undifferentiated cells capable of dividing and differentiating into the ear tissue. the objective of the present study is to isolate, culture expand...
