The Stem Cell
Concept
A stem cell is an undifferentiated,
dividing cell that gives rise to a
daughter cell like itself and a
daughter cell that becomes a
specialized 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 Parkinson's 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 to
produce 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)

Histology of donor testes. In calves with SC between 18-20 cm, 45% of tubules
contained a single layer of epithelium composed of Spermatogonia (arrows) and
Sertoli cells (arrowhead) (A), while the remaining tubuleswerecomposedof2–4 layers
with spermatocytes (arrows) (B). In calves with SC between 21 and 22 cm, nearly
53% of tubules contained 4–6 layers epithelium and spermatogenesis had
progressed to Production of spermatids (arrow) (C). Bar Z 50 mm. Herrid et al.

Analysis of differentiation of SSC1 cells in vivo. (A) A fluorescent microscopic picture of a section of a 3 week transplanted testis
showed proliferation of GFP positive cells (2.1% of tubuli). (B) Eight weeks after transplantation, GFP positive cells migrated to the
basement membrane and colonized the tubules (3.8 colonies per 107 cells). These cells were able to initiate spermatogenesis and to
differentiate into spermatids after 3 months (D) and into mature sperm after 7 months (F) of transplantation (3.0 colonies per 107
cells). A higher magnification of a spermatid and a sperm cell are shown at the right corner of the pictures. The other non-transplanted
testis served as an internal control (C and E), no regeneration of spermatogenesis was observed. Hemalaun-eosin staining (G) and the
corresponding fluorescence picture (H) showed the GFP positive cells in the periphery of seminiferous tubules (arrow) and their
differentiation into sperm (arrow). A higher magnification of a sperm cell is shown at the right corner of the picture. (I) RT–PCR
analysis 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 SSC1
cells were differentiated into postmeiotic cells. For control, RNA from SSC1 cells and testicular RNA (T) were used. GAPDH served as an
internal standard. (J) DNA image cytometry analysis. The DNA contents were quantified by assigning an optical density to each pixel in
the 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 to
indirect immunofluorescence with antibodies to outer acrosomal membrane protein (L) and transition protein 2 (M) as primary
antibodies and Cy3-conjugated (red) secondary IgG antibodies. Positive cells are shown (arrows).

        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 to
program bone marrow stem cells to repair damaged retinas in mice, suggesting a
potential treatment for one of the most common causes of vision loss in older
people.
Functional mesenchymal stem cells
derived from human induced pluripotent
stem 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.

  • 14. Stem cell based therapeutical approach of male infertility by teratocarcinoma derived germ cells Nayernia et al., 2004. Human Molecular Genetics 13, (14):1451–1460 Analysis of differentiation of SSC1 cells in vivo. (A) A fluorescent microscopic picture of a section of a 3 week transplanted testis showed proliferation of GFP positive cells (2.1% of tubuli). (B) Eight weeks after transplantation, GFP positive cells migrated to the basement membrane and colonized the tubules (3.8 colonies per 107 cells). These cells were able to initiate spermatogenesis and to differentiate into spermatids after 3 months (D) and into mature sperm after 7 months (F) of transplantation (3.0 colonies per 107 cells). A higher magnification of a spermatid and a sperm cell are shown at the right corner of the pictures. The other non-transplanted testis served as an internal control (C and E), no regeneration of spermatogenesis was observed. Hemalaun-eosin staining (G) and the corresponding fluorescence picture (H) showed the GFP positive cells in the periphery of seminiferous tubules (arrow) and their differentiation into sperm (arrow). A higher magnification of a sperm cell is shown at the right corner of the picture. (I) RT–PCR analysis 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 SSC1 cells were differentiated into postmeiotic cells. For control, RNA from SSC1 cells and testicular RNA (T) were used. GAPDH served as an internal standard. (J) DNA image cytometry analysis. The DNA contents were quantified by assigning an optical density to each pixel in the 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 to indirect immunofluorescence with antibodies to outer acrosomal membrane protein (L) and transition protein 2 (M) as primary antibodies and Cy3-conjugated (red) secondary IgG antibodies. Positive cells are shown (arrows).

  • 25. Functional mesenchymal stem cells derived from human induced pluripotent stem 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.  By Lian Q, Zhang Y, Zhang J, Zhang HK, Wu X, Zhang Y, Lam FF, Kang S, Xia JC, Lai WH, Au KW, Chow YY, Siu CW, Lee CN, Tse HF.
