This study was undertaken to determine the proportions and in vitro immune capacities of lymphocyte populations in the bone marrows of normal humans. Relatively pure mononuclear cell suspensions were obtained from bone marrow aspirates by linear sucrose gradient centrifugations. Simultaneous peripheral blood and bone marrow specimens from each individual were assayed for lymphocyte surface mark...
The use of marrow aspirates in bone marrow transplantation. clinical evaluation. and experimental studies has prompted the present study of the functional characteristics of mononuclear cells from aspirated (iliac crest) and curettaged (rib) marrow. In this manner. the relative contribution of peripheral blood contamination of aspirated bone marrow cells in investigating and understanding marro...
Objective- To investigate the effect of intratendinous injection of bMSCs on the rate and extent of tendon healing after primary repair in a rabbit model. Design- Experimental study. Animals- Twenty seven skeletally mature New Zealand white rabbits weighing 1.8- 2.5 kg were used. Twenty rabbits were used as the experimental animals, and seven others were used as a source of bone marrow-derived ...
purpose: to separate and characterize orbital fat-derived stem cells (ofscs) and compare its cellular and molecular properties with those of bone marrow-derived mesenchymal stem cells (mscs) and adipose-derived stem cells (ascs). methods: stem cells from orbital fat, abdominal fat and bone marrow aspirates have been isolated. we assessed stem cell specific cell surface markers using cytometry, ...
Objective—Although some patients with limb ischemia have recently undergone therapeutic angiogenesis by cell transplantation, their angiogenic potential has not been well characterized. It is also important to evaluate endothelial progenitor cell (EPC) contents in different stem cell sources to choose the best material for therapeutic angiogenesis. Methods and Results—We quantitated the mRNA ex...
background: spinal cord has a limited capacity to repair therefore, medical interventions are necessary for treatment of injuries. transplantation of schwann cells has shown a great promising result for spinal cord injury (sci). however, harvesting schwann cell has been limited due to donor morbidity and limited expansion capacity. furthermore, accessible sources such as bone marrow stem cells ...
hematopoietic stem/progenitor cells (hspcs) which give rise to different blood cell types are present within the bone marrow microenvironment, especially in flat bones such as skull, vertebrae, pelvis and chest. interacting factors such as stromal derived factor-1/cxcr4, very late antigen-4/vascular cell adhesion molecule-1, lymphocyte function-associated antigen-1/ intercellular adhesion molec...
Introduction: In this study the effect of vitreous humor on the mesenchymal stem cells (MSCs) derived from bone marrow to lens fiber-like cells was investigated. Methods: In this experimental study bone marrow cells were collected by flushing femurs and tibias in NMRI mice. Immunocytochemistry by Oct4 antibody was used to confirm that the cells are stem cells. The mesenchymal character of thes...
Bone tissue engineering has been one of the most promising areas of research, providing a potential clinical application to cure bone defects. Recently, various stem cells, including embryonic stem cells (ESCs), bone marrow-derived mesenchymal stem cells (BM-MSCs), umbilical cord blood-derived mesenchymal stem cells (UCB-MSCs), adipose tissue-derived stem cells (ADSCs), muscle-derived stem cell...
The hypothesis that bone marrow– derived, circulating endothelial cells incorporate into tumor blood vessels is unresolved. We have measured the numbers of bone marrow–derived versus resident endothelial cells in spontaneous prostate cancers during different stages of tumor progression and in age-matched normal prostates. Bone marrow–derived endothelial cells were rare in dysplasia and in well ...
