The Stem CellConceptA stem cell is an undifferentiated,dividing cell that gives rise to adaughter cell like itself and adaughter cell that becomes aspecialized cell type.
Cell Therapy A treatment intended to regenerate or rejuvenate the body by injecting it with healthy live or freeze-dried cells derived from organs or embryos. Sometimes called fresh or live cell therapy. Performed to treat specific diseases and disorders: arthritis, lupus, cancer, HIV infection, cardiovascular and neurological disorders, and Parkinsons disease. Also used to stimulate the immune system, revitalize bodily organs, and slow the effects of aging, including memory loss and sexual dysfunction.

Tissue engineering and therapeutic cloning in an effort toproduce genetically identical renal tissue in an animal model(Bos taurus) Bovine skin fibroblasts from adult Holstein steers were obtained by ear notch and single donor cells were isolated and microinjected into the perivitelline space of donor enucleated oocytes (nuclear transfer). Blastocysts were transferred to the uterus of progestin- synchronized recipients permit further in vivo growth. After 12 weeks cloned renal cells were harvested, expanded in vitro, then seeded onto biodegradable scaffolds. The constructs (consisting of cells + scaffolds) were then implanted into the subcutaneous space of the same steer from which the cells were cloned to allow for tissue growth (Hipp and Atala 2004)

In calves with SC between 18-20 cm, 45% of tubulescontained a single layer of epithelium composed of Spermatogonia (arrows) andSertoli cells (arrowhead) (A), while the remaining tubuleswerecomposedof2–4 layerswith spermatocytes (arrows) (B). In calves with SC between 21 and 22 cm, nearly53% of tubules contained 4–6 layers epithelium and spermatogenesis hadprogressed to Production of spermatids (arrow) (C). Bar Z 50 mm.

Stem cell based therapeutical approach of male infertility by teratocarcinoma derived germ cells Nayernia et al., 2004. Human Molecular Genetics 13, (14):1451–1460Analysis of differentiation of SSC1 cells in vivo. (A) A fluorescent microscopic picture of a section of a 3 week transplanted testisshowed proliferation of GFP positive cells (2.1% of tubuli). (B) Eight weeks after transplantation, GFP positive cells migrated to thebasement membrane and colonized the tubules (3.8 colonies per 107 cells). These cells were able to initiate spermatogenesis and todifferentiate into spermatids after 3 months (D) and into mature sperm after 7 months (F) of transplantation (3.0 colonies per 107cells). A higher magnification of a spermatid and a sperm cell are shown at the right corner of the pictures. The other non-transplantedtestis served as an internal control (C and E), no regeneration of spermatogenesis was observed. Hemalaun-eosin staining (G) and thecorresponding fluorescence picture (H) showed the GFP positive cells in the periphery of seminiferous tubules (arrow) and theirdifferentiation into sperm (arrow). A higher magnification of a sperm cell is shown at the right corner of the picture. (I) RT–PCRanalysis of transplanted testis (TR) 3 months after transplantation, compared with a germ cell depleted but non-transplanted testis(NTR). Expression of genes specific for premeiotic (EGFP, Stra8), meiotic (SCP3, Pgk2) and postmeiotic (Tp2) stages shows that SSC1cells were differentiated into postmeiotic cells. For control, RNA from SSC1 cells and testicular RNA (T) were used. GAPDH served as aninternal standard. (J) DNA image cytometry analysis. The DNA contents were quantified by assigning an optical density to each pixel inthe image and summing the optical density values for each nucleus. One hundred cells in luminal layer of the same sections in (G) and(H) were evaluated for DNA ploidy analysis. The presence of a haploid cell population (arrow) was confirmed. (K) As reference cells,mouse epidermis and lymphocytes were measured. (L and M) Characterization of differentiated cells. Testis sections were subjected toindirect immunofluorescence with antibodies to outer acrosomal membrane protein (L) and transition protein 2 (M) as primaryantibodies and Cy3-conjugated (red) secondary IgG antibodies. Positive cells are shown (arrows).

Shindo A, Nakamura T, Matsumoto Y, Kawai N, Okano H, Nagao S, Itano T, Tamiya T. ScienceDaily (Aug. 30, 2008) — Oregon Health & Science University scientists have successfully produced functional auditory hair cells in the cochlea of the mouse inner ear. The breakthrough suggests that a new therapy may be developed in the future to successfully treat hearing loss. The results of this research was recently published by the journal Nature.ScienceDaily (Aug. 3, 2009) — University of Florida researchers were able toprogram bone marrow stem cells to repair damaged retinas in mice, suggesting apotential treatment for one of the most common causes of vision loss in olderpeople.
Functional mesenchymal stem cellsderived from human induced pluripotentstem cells attenuate limb ischemia in mice Human iPSCs were induced to MSC differentiation with a clinically compliant protocol. Three monoclonal, karyotypically stable, and functional MSC-like cultures were successfully isolated using a combination of CD24(-) and CD105(+) sorting. They did not express pluripotent-associated markers but displayed MSC surface antigens and differentiated into adipocytes, osteocytes, and chondrocytes. Transplanting iPSC-MSCs into mice significantly attenuated severe hind-limb ischemia and promoted vascular and muscle regeneration. The benefits of iPSC-MSCs on limb ischemia were superior to those of adult bone marrow MSCs. The greater potential of iPSC-MSCs may be attributable to their superior survival and engraftment after transplantation to induce vascular and muscle regeneration via direct de novo differentiation and paracrine mechanisms. Functional MSCs can be clonally generated, beginning at a single-cell level, from human iPSCs. Patient-specific iPSC-MSCs can be prepared as an "off-the-shelf" format for the treatment of tissue ischemia.
