In the current study, immunohistochemical staining of the pancreas of diabetic dogs that received intrahepatic undifferentiated or differentiated MSCs showed a significant increase in the area % of insulin immunoreactive cells compared with the positive control group, which showed a loss of β cells and the insulin immunoreactivity was scattered, if any. What obstacles need to be addressed before the "therapeutic promise" of stem cells can be realized? Understanding the differences between: adult stem cells, embryonic stem cells, IPS cells. J Pharmacol Exp Ther. One day before transfection, 0.5–2 × 105 cells were plated in 500 ml of growth medium without antibiotic per well so that they will be 90–95% confluent at the time of transfection, and then DNA lipofectamine 2000 complexes were prepared. Immunofluorescent technique, × 400. However, the use of ESCs in a clinical setting is limited. Stem cell definition, a cell that upon division replaces its own numbers and also gives rise to cells that differentiate further into one or more specialized types, as various B cells and T cells. Data is temporarily unavailable. The definition of oval cells largely derives from experimental paradigms in animals, and it seems clear that some hematopoietic stem cells are also capable of differentiating into hepatocytes. The mononuclear cell layer was carefully transferred at a new 50 ml conical tube, the tube was filled with RPMI to 10 cm, and then centrifuged; the precipitation was completed with RPMI to 1 cm. Stem cells: active, undifferentiated cells found at the base of lamina propria. Mesenchymal stem cells: clinical applications and biological characterization. Unfortunately, islet transplantation has historically been hampered by immune rejection and the scarcity of donor islets [23,24]. Purification and ex vivo expansion of postnatal human marrow mesodermal progenitor cells. Exendin-4 could stimulate both β-cell replication and neogenesis from ductal progenitor cells, and inhibit the apoptosis of β cells [44,45]. 800-638-3030 (within USA), 301-223-2300 (international). Glucose levels were monitored by tapped leg vein blood under fasting condition every day after transplantation for 7 days. The dogs were acclimatized to laboratory conditions and fed a basal diet formed of ordinary bread, fresh milk, and different vegetables, with a liberal supply of water; they were divided into two major groups. In the present study, H&E staining of the tail of the pancreas of diabetic dogs showed a reduction in the size and number of islets, loss of uniform cellular organization, necrotic changes in pancreatic islets, nuclear changes and karyolysis. Morphometric measurements were carried out in the Histology Department, Faculty of Medicine, Cairo University.

The pancreas showed a histological structure similar to that of group IIB; some islets were atrophic, whereas others showed hypertrophic cells with large vesicular nuclei (Fig. All animals were provided with food and water, maintained at 25–28°C and were housed in … Human adipose tissue-derived mesenchymal stem cells differentiate into insulin, somatostatin and glucagon expressing cells. Tissue specimens were embedded in paraffin and stained with H&E [21]. These cells are monocyte-macrophage in origin and fuse to form a multinucleated osteoclast. dividing stem cells, to the surface epithelium where they eventually undergo apoptosis. Recent studies have demonstrated the feasibility of generating IPCs obtained from progenitor cells of various cellular sources, including the pancreas [35,36], the liver [37] and intestinal epithelium [38], adipose tissue-derived stem cells [39] and pluripotent ESCs of mouse [20,40] and human [41] origins. Several in-vitro studies have shown that bone marrow-derived stem cells could be reprogrammed to become functionally IPCs under certain culture conditions [20,33,34]. Please try again soon. I.

(More? Bone marrow as a potential source of hepatic oval cells. Immunohistochemistry: peroxidase antiperoxidase, × 400. BM-MSCs reside in the bone marrow, and can differentiate into lineages of mesenchymal tissues such as bone, cartilage, fat, tendon, muscle, adipocytes, chondrocytes, osteocytes [13,10,11,14–27], and also into endodermal and epidermal cells, such as vascular endothelial cells, neurocytes, lung cells, and hepatocytes [28–30]. Nine adult male dogs were obtained from the animal house of the Faculty of Veterinary Medicine, Cairo University. Drucker DJ. Pancreatic islet transplantation has sparked new interest in the treatment of DM. Flow cytometric analysis of the immunophenotype of the MSCs showed that these cells were negative for CD34 and expressed high levels of CD44. Stem cells serve as an internal repair system; when a stem cell divides, each resulting cell has the potential to either remain a stem cell or become another type of cell with a more specialized function, such as a muscle cell, a red blood cell, or a brain cell [9]. How are "totipotent", "multipotent" and "pluripotent" defined and how do these terms relate to stem cells? Rinehart and Farquhar first discovered FS cells through electron microscopy of the anterior pituitary gland.

An alternative for islet transplantation would involve the use of a renewable source of stem cells capable of self-renewal and differentiation, and capable of insulin production [20]. Her previous project was 'BMSCs 3D coculture inhibit liver fibrosis key player hepatic stellate cells'. MSCs have high multiplication potency; their cell-doubling time is 48–72 h, and cells could be expanded in culture for more than 60 doublings [31]; MSC donors (autologous transplantation) would not cause any rejection [32]. 10). No files in this folder. The present study was designed to test the therapeutic effect and the role of the regeneration capacity of MSCs from the bone marrow in diabetic dogs. Stem cells have been the object of much excitement and controversy amongst both scientists and the general population. For more information, please refer to our Privacy Policy. The dogs were fasted for 12 h before and after the injection of alloxan; the unfed animals are more susceptible to alloxan-induced diabetes [48,49].

Each dog was sacrificed with an overdose of sodium pentobarbital at 7 days after implantation. 17). In the present study, MSCs were marked with green fluorescence protein, which can be visualized easily by fluorescence microscopy. Glucose is a growth factor for β cells; it induces in-vitro differentiation of adult hepatic stem cells into pancreatic endocrine hormone-producing cells and increases the insulin content in cell lines derived from ESCs [40–43]. The surface and gastric pit cells are constantly surrounded by a very harsh environment and so have a high cell turnover of only 4 to 7 days, while the turnover of the cells in the gastric glands is slower. The pancreas showed less organized pancreatic islets. Significant increase was observed in insulin immunoreactive cells of the pancreas and the liver of groups that received undifferentiated and differentiated MSCs (P < 0.05) as compared with the +ve control. Wild S, Roglic G, Green A, Sicree R, King H. Global prevalence of. Several studies seem to support the conclusion that the endocrine precursor cells are present not only in the duct but also within the islets themselves [15]. Course material for the second part of the Course that deals with the biology of stem cells and their clinical applications is entirely in English. This group showed a decreased size of the islets of Langerhans (atrophied islets), loss of uniform cellular distribution, fewer cells, vacuolated cytoplasm, pyknotic nuclei, and perivascular inflammatory cells. What obstacles need to be addressed before the "therapeutic promise" of stem cells can be realized. 6). Histology of Stem Cells A lecture for Medical Students. Group II (eight dogs) diabetic models received a single intravenous injection of alloxan (50 mg/kg) to induce diabetes, and were further subdivided into three subgroups: subgroup IIA (two dogs) served as the +ve control, subgroup IIB (two dogs) received undifferentiated MSCs at a dose of 5 × 106 intrahepatic percutaneously, and subgroup IIC (four dogs) also received the same dose of differentiated MSCs (IPCs). 1999;5:267–277, Wakitani S, Goto T, Pineda SJ, Young RG, Mansour JM, Caplan AI, Goldberg VM.
