INTRODUCTION Relatively little is known about cellular subpopulations in the mature nucleus pulposus (NP). Detailed understanding of the ontogenetic, cellular and molecular characteristics of functional intervertebral disc (IVD) cell populations is pivotal to the successful development of cell replacement therapies and IVD regeneration. In this study, we aimed to investigate whether phenotypica...

Fully human antibodies have minimal immunogenicity and safety profiles. At present, most potential antibody drugs in clinical trials are humanized or fully human. Human mostly generated using the phage display method (in vitro) by transgenic mice vivo); other methods include B lymphocyte immortalization, human–human hybridoma, single-cell polymerase chain reaction. Here, we describe a structure...

Cancer testis antigens (CTAs), a large family of tumor-associated and immunogenic antigens expressed in human tumors of various histological origins, are highly restricted to the testis and trophoblast. CTAs have been identified as potent targets for tumor-specific immunotherapeutic advances and have immensely lead to the development of different clinical trials of CTA-based vaccine therapy bec...

Leukemia cells from a patient with chronic lymphocytic leukemia (CLL) were found to bind sheep RBC (SRBC) through their monoclonal surface IgM. A lymphoblastoid cell line was obtained by immortalization of leukemic cells with Epstein-Barr virus (EBV). Cultured leukemic cells were found to have a supernumerary chromosome 12, an abnormality typical of CLL of the B cell type. To our knowledge, thi...

Liver regeneration after partial hepatectomy results primarily from the simple division of mature hepatocytes. However, during embryonic and fetal development or in circumstances under which postnatal hepatocytes are injured, organ regeneration is believed to occur from a compartment of epithelial liver stem or progenitor cells with biliary and hepatocytic bipotentiality. The ability to identif...

Abnormal methylation of CpG island sequences on chromosomes 11p and 17p, and tumor phenotype-associated differential methylation of chromosome 3p loci have been described in human lung tumors (S.B. Baylin, J.W.M. Hoppener, A. de Bustros, P.H. Steenbergh, C.J.M. Lips, and B. D. Nelkin, Cancer Res., 46: 2917-2922, 1986; M. Makos, B.D. Nelkin, M. I. Lerman, F. Latif, B. Zbar, and S.B. Baylin, Proc...

Isolation and expansion of neural stem cells (NSCs) of human origin are crucial for successful development of cell therapy approaches in neurodegenerative diseases. Different epigenetic and genetic immortalization strategies have been established for long-term maintenance and expansion of these cells in vitro. Here we report the generation of a new, clonal NSC (hc-NSC) line, derived from human ...
