Human umbilical cord blood (UCB) contains hematopoietic stem cells (HSCs) and mesenchymal stem cells (MSCs), both of which are regarded as valuable sources for cell transplantation and cell therapy. Adherent cells expressing MSCs-related antigens such as SH2, CD13, CD29, and ASMA, have been isolated from a mononuclear cell fraction of human UCB. Under(More)
In addition to long-term self-renewal capability, human mesenchymal stem cells (MSCs) possess versatile differentiation potential ranging from mesenchyme-related multipotency to neuroectodermal and endodermal competency. Of particular concern is hepatogenic potential that can be used for liver-directed stem cell therapy and transplantation. In this study,(More)
Human umbilical cord blood (UCB) has been regarded as an alternative source for cell transplantation and cell therapy because of its hematopoietic and nonhematopoietic (mesenchymal) potential. Although there has been debate about whether mesenchymal stem cells (MSCs) are invariably present in UCB, several reports showed that MSC-like cells could be(More)
Mesenchymal stem cells (MSCs) retain both self-renewal and multilineage differentiation capabilities. Despite wide therapeutic potential, many aspects of human MSCs, particularly the molecular parameters to define the stemness, remain largely unknown. Using high-density oligonucleotide micro-arrays, we obtained the differential gene expression profile(More)
Human mesenchymal stem cells (hMSCs) have been paid a great deal of attention because of their unprecedented therapeutic merits endowed by powerful ex vivo expansion and multilineage differentiation potential. Umbilical cord blood (UCB) is a convenient but not fully proven source for hMSCs, and hence, greater experience is required to establish UCB as a(More)
The mouse B-cell lymphoma WEHI 279.1 is a tumor which synthesizes both membrane and secreted immunoglobulin M (IgM). We have immunoselected variants which fail to express the membrane form (mIgM−); the most frequently isolated phenotype is a complete loss of both membrane expression and synthesis of the μ heavy chain within the cells. We have chosen four of(More)
