conclusions our findings showed that the treatment of flaps with bm-msc and aam transplantations significantly promoted flap survival compared to a control group. the viability of the flap was improved by combining bm-mscs with aam matrix scaffolds. materials and methods bm-mscs and aams were transplanted into subcutaneous tissue in the flap area. on the 7th postoperative day, the surviving fla...

OBJECTIVE To investigate the differentiation of bone marrow stromal cells (BMSC) into neuron-like cells and to explore their potential use for neural transplantation. METHODS BMSC from rats and adult humans were cultured in serum-containing media. Salvia miltiorrhiza was used to induce human BMSC (hBMSC) to differentiate. BMSC were identified with immunocytochemistry. Semi-quantitative RT-PCR...

The aim of this study was to evaluate whether transplantation of Schwann cells derived from bone marrow stromal cells (BMSC-SCs) promotes axonal regeneration and functional recovery in completely transected spinal cord in adult rats. Bone marrow stromal cells (BMSCs) were induced to differentiate into Schwann cells in vitro. A 4-mm segment of rat spinal cord was removed completely at the T7 lev...

background: recent reports demonstrated that intravenous route as a minimally invasive method, similar to direct injection, is suitable for bone marrow stromal cell (bmsc) transplantation. in this study, we made a comparison of intraspinal and intravenous route of bmsc administration to repair injured spinal cord tissue. methods: six groups of adult female rats were used in this study. laminect...

One of the applications of bone marrow stromal cells (BMSCs) that are produced by ex vivo expansion is for use in in vivo bone tissue engineering. Cultured stromal cells are a mixture of cells at different stages of commitment and expansion capability, leading to a heterogeneous cell population that each time can differ in the potential to form in vivo bone. A parameter that predicts for in viv...

UNLABELLED Annexin 2 (ANXA2) plays a critical role in hematopoietic stem cell (HSC) localization to the marrow niche. In part, ANXA2 supports HSCs by serving as an anchor for stromal-derived factor-1 (CXCL12/SDF-1). Recently, it was demonstrated that prostate cancer cells, like HSCs, use ANXA2 to establish metastases in marrow. The present study determined the capacity of ANXA2 expression by bo...

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...

introdution: stroke is one of the most common diseases caused by occlusion or rupture of blood vessels in brain. it brings heavily loads for families and societies. although some new strategies including treatment of tissue plasminogen activator have been applied in the clinic, these methods do not have perfect effect. accordingly, more effective therapeutic strategies need to be developed. thi...

BACKGROUND Migration, proliferation, and differentiation of hematopoietic stem cells (HSCs) are dependent upon a complex three-dimensional (3D) bone marrow microenvironment. Although osteoblasts control the HSC pool, the subendosteal niche is complex and its cellular composition and the role of each cell population in HSC fate have not been established. In vivo models are complex and involve su...
