Induction of Pluripotent Stem Cells from Adult Human Fibroblasts by Defined Factors

Human blastocyst-derived, pluripotent cell lines are described that have normal karyotypes, express high levels of telomerase activity, and express cell surface markers that characterize primate embryonic stem cells but do not characterize other early lineages. After undifferentiated proliferation in vitro for 4 to 5 months, these cells still maintained the developmental potential to form trophoblast and derivatives of all three embryonic germ layers, including gut epithelium (endoderm); cartilage, bone, smooth muscle, and striated muscle (mesoderm); and neural epithelium, embryonic ganglia, and stratified squamous epithelium (ectoderm). These cell lines should be useful in human developmental biology, drug discovery, and transplantation medicine.

Core transcriptional regulatory circuitry in human embryonic stem cells.

A murine monoclonal antibody 602-29, subclass IgG1, that recognizes an antigenic determinant expressed by most human cells is described. Immunoprecipitation and sodium dodecyl sulfate-gel electrophoresis analysis indicate that the antigenic determinant is carried by a protein with an apparent molecular weight of 21,000. The antigen is expressed by human-mouse somatic cell hybrids, and analysis of segregants that have lost human chromosomes indicates that the gene controlling expression of the 602-29 antigen is on chromosome 12.

Glycolipids of human germ cell tumor lines were analyzed co define the most common immunohistochemical profiles of embryonal carcinoma (EC), differentiated derivatives of EC, yolk sac carcinoma (YC) and choriocarcinoma (CC). Glycolipid composition was examined by high-performance thin-layer chromatography (HPTLC) combined with Immunostaining with a panel of anti-carbohydrate monoclonal antibodies (MAbs). All EC cell lines were found to contain high levels of globo-series glycolipids, including globotriosylceramide (Gb3), globoside (Gb4), Gb5 (Ga1β1 ± 1Gb4) and GL7 (sialyl Ga1β1 ± 3Gb4). Somatic differentiated derivatives (e.g., EC cells treated with retinoic acid) contained decreased levels of globo-series glycolipids and increased levels of lacto- and ganglio-series glycolipids, including GD3, GT3 and GD2. CC cell lines contained relatively large amounts of Gb3 but did not contain extended globo-series glycolipids GbS and GL7. CC cell lines also contained a macroglycolipid reactive with the antibody to SSEA-1 (Lex). Glycolipids were not detected in two YC cell lines, while other YC cell lines contained globo-series core glycolipids (Gb3 and Gb4) and gangliosides. We conclude that EC, YC and CC have distinct patterns of membrane glycolipid expression that can be identified by HPTLC and immunostaining. Our results indicate that globo-series glycolipids GbS and GL7, which carry stage-specific embryonic antigens 3 and 4 (SSEA-3 and SSEA-4), are a hallmark of human EC cells. Cell lines derived from human germ cell tumors that do not express Gb5 and GL7 deserve to be re-evaluated, since they may represent different stem cells, most likely equivalent to somatic cells and their developmentally committed precursors (e.g., neuroblasts). © 1994 Wiley-Liss, Inc.

Glycolipids of germ cell tumors: extended globo-series glycolipids are a hallmark of human embryonal carcinoma cells.

BACKGROUND Testicular cancer is preceded by the noninvasive stage of carcinoma in situ (CIS). According to a recent hypothesis, testicular CIA cells are germ cells transformed in fetal life. The idea of an embryonal origin of testicular germ cell neoplasia would be strengthened by the finding of antigenic similarity between fetal germ cells, CIS cells, and invasive testicular germ cell tumors. METHODS Monoclonal antibody (MoAb) TRA-1-60 raised against a human embryonal carcinoma cell line was immunohistochemically tested on 21 fetal gonads (11 male gonads and 10 female gonads; 11th-24th week of gestation). In addition, TRA-1-60 was tested on tissue from 27 testes with CIS, 11 testes with invasive testicular cancer, and 24 adult and 4 infant testicular control specimens. RESULTS Expression of TRA-1-60 was found in germ cells of six female and two male fetal gonads. In addition, 26 of 27 adult human testes with CIS, 7 of 8 seminomas, and 3 of 3 embryonal carcinomas were TRA-1-60 positive. CONCLUSIONS The study demonstrated an antigenic link between fetal germ cells, cells of CIS and seminomas, and embryonal carcinomas. The results provided additional evidence for the hypothesis that testicular neoplasia arises during early fetal life and CIS cells are malignant fetal gonocytes.

Somatic cell reprogramming holds great promise for the development of novel cellular therapeutics. A number of sources of reprogramming potential have been identified, including oocytes, embryonic germ (EG) cells and embryonic stem (ES) cells. However, each of these sources of reprogramming factors is problematic, since they are either not freely available or have special growth requirements. Embryonal carcinoma (EC) cells are another source of pluripotent cells that, unlike ES and EG cells, do not usually require special growth conditions. Since they share many of the key characteristics of ES cells, such as pluripotency, EC cells may provide a readily amenable alternative source of reprogramming factors and could serve as a model for ES cells in this respect. Here we show that mouse EC cells can also function as donors of reprogramming factors. PEG-mediated fusion between murine EC cells (P19) and the cells of a human T-lymphoma cell line (CEM-GFP) resulted in inter-species hybrid colony formation. Colo...
