Little is known about how hematopoietic stem cells (HSCs) self-renew. We studied the regeneration of HSCs in culture. Effects of various cytokines on cell division of CD34(-/low) c-Kit(+)Sca-1(+) lineage marker-negative (CD34(-)KSL) bone marrow cells of the mouse were first evaluated in serum-free single cell culture. We then performed a competitive repopulation assay on divided cells to ask if such cell division involved self-renewal of HSCs.In the presence of stem cell factor (SCF), thrombopoietin (TPO) induced a first cell division of CD34(-)KSL cells more efficiently than did interleukin (IL)-3 or IL-6. Multilineage repopulating cells were detected in a significant proportion of cells derived from single cells in culture with TPO and SCF, although this culture condition led to a substantial decrease in HSC number. These regenerated repopulating cells could be further transplanted into secondary recipients. When paired daughter cells were separately studied, one of a pair gave rise to repopulating cells with self-renewal potential, suggesting asymmetric self-renewal division. This study provides evidence that one HSC regenerates at least one HSC in culture.

We report a 35-year-old pregnant woman with progressive subcutaneous panniculitis-like T-cell lymphoma (SPTCL). During pregnancy chemotherapy with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) stabilized the disease for 4 months before new manifestations appeared. After delivery of a healthy girl, myeloablative radiochemotherapy followed by autologous stem cell transplantation could be performed leading to complete remission.

A ligand of human thy-1 is localized on polymorphonuclear leukocytes and monocytes and mediates the binding to activated thy-1-positive microvascular endothelial cells and fibroblasts.

Thy-1 is known to be expressed on fibroblasts, nerve cells, and blood stem cells. Previous studies have shown the induction of Thy-1 on phorbol ester stimulated human dermal microvascular endothelial cells in vitro. In situ Thy-1 expression was found on activated endothelium. In this study we were interested in the localization of a Thy-1 ligand and the characterization of the function of Thy-1 on human dermal microvascular endothelial cells and fibroblasts. Human Thy-1 purified from fibroblast extracts was labeled and used as a probe for the detection of a Thy-1 ligand. In cryostat sections of bullous pemphigoid skin a Thy-1 ligand was found on inflammatory cells, whereas the Thy-1 antigen was expressed on the endothelial cells and fibroblasts. By flow cytometry we could show the expression of a Thy-1 ligand on polymorphonuclear leukocytes and monocytes, whereas lymphocytes did not express this Thy-1 ligand. To study whether Thy-1 is involved in cell-cell adhesion we separated Thy-1-positive and Thy-1-negative cells by magnetic cell separation using the monoclonal antibody AS02. Cell adhesion assays and blocking experiments revealed a direct involvement of the Thy-1/Thy-1 ligand interaction in the binding of monocytes and polymorphonuclear leukocytes to Thy-1-positive activated endothelial cells and fibroblasts.

Pluripotent, cytokine-dependent, hematopoietic stem cells are immortalized by constitutive Notch1 signaling.

Hematopoietic stem cells give rise to progeny that either self-renew in an undifferentiated state or lose self-renewal capabilities and commit to lymphoid or myeloid lineages. Here we evaluated whether hematopoietic stem cell self-renewal is affected by the Notch pathway. Notch signaling controls cell fate choices in both invertebrates and vertebrates by inhibiting certain differentiation pathways, thereby permitting cells to either differentiate along an alternative pathway or to self-renew. Notch receptors are present in hematopoietic precursors and Notch signaling enhances the in vitro generation of human and mouse hematopoietic precursors, determines T- or B-cell lineage specification from a common lymphoid precursor and promotes expansion of CD8(+) cells. Here, we demonstrate that constitutive Notch1 signaling in hematopoietic cells established immortalized, cytokine-dependent cell lines that generated progeny with either lymphoid or myeloid characteristics both in vitro and in vivo. These data support a role for Notch signaling in regulating hematopoietic stem cell self-renewal. Furthermore, the establishment of clonal, pluripotent cell lines provides the opportunity to assess mechanisms regulating stem cell commitment and demonstrates a general method for immortalizing stem cell populations for further analysis.

Developmental changes of CD34 expression by murine hematopoietic stem cells.

It has been reported that fetal murine hematopoietic stem cells are CD34(+), whereas adult stem cells are CD34(-). We sought to delineate the developmental changes of CD34 expression by hematopoietic stem cells and carried out systematic analysis of long-term engrafting cells in the bone marrow and/or blood of perinatal, juvenile, and adult mice.To obtain information on the total population of stem cells, we prepared CD34(+) and CD34(-) populations of mononuclear cells without prior enrichment and assayed their long-term reconstituting abilities by transplantation into lethally irradiated Ly-5 congenic mice.All stem cells from perinatal to 5-week-old mice were CD34(+). In 7-week-old mice, CD34(-) stem cells began to emerge, and the majority of the stem cells were CD34(-) in the 10- and 20-week-old mice. Approximately 20% of adult stem cells expressed CD34. Developmental changes of CD34 expression from the positive to the negative state takes place between 7 and 10 weeks of age for the majority of murine stem cells. Approximately 20% of adult stem cells remain CD34(+). These observations provide insight into the current controversy regarding CD34 expression by adult hematopoietic stem cells and suggest that the majority of stem cells in human umbilical cord blood and bone marrow of young children are CD34(+).

The average human scalp is covered by approximatey 100,000 hair follicles. Each hair undergoes hair cycle and normally 50-100 hairs randomly fall out a day, which is unnoticeable because lost hair is replaced by as many new hairs springing up daily. Hair loss results from the fall out of hair from the hair follicle. Alopecia or excessive, premature hair loss is the condition caused by many factors. Loss of hair itself does not pose critical health problems because biological role of human hair is relatively marginal. Hair on our scalp protects the head from mechanical shock, heat loss, and exposure to UV-light. The eyelashes and eyebrowes protect the eyes, and hair in the ear canal or the nasal passages help filter out particles and pathogens, thus protecting our internal organs. However, hair does play important social role: it is one of the major determinants of our appearance and identity in daily life. Fullness of hair also implicates or manifests physical integrity and youthfulness of the person. Losing hair could have more than just emotional impacts on individuals. The hair is a unique organ that goes through a characteristic cycle consisting of an immature phase, a growing phase called anagen, a transitional phase between the growing phase and the resting phase called catagen, and finally a resting phase called telogen in which the hair stops growing, waiting to fall out. 85-90% of hairs on our body are in anagen phase or growing phase, which lasts anywhere from two to five years. This phase is followed by a short regression phase, or catagen, which lasts 2-3 weeks. Approximately 1% of hair follicles are in catagen. Approximately 10-15% of hair follicles are in the resting phase, the telogen, which lasts about 3-5 months. Hair follicles typically goes through 10-20 asynchronous cycles during the lifetime. Persistent loss of more than 150 hairs would consist a state of hair loss, or alopecia, albeit it could be temporary.

DHEA is a natural hormone, and it is produced in our body by the adrenal glands. DHEA has been suggested to provide numerous potential benefits. DHEA (or dehydroepiandrosterone) is converted into androgens (male hormones) or estrogens (female hormones) in the cells. Our bodies produce decreasing amount of DHEA as we get older. various health benefits: To deter aging, improve sexual function/erectile dysfunction, treat cognitive decline, enhance athletic performance, facilitate weight loss, improve strength, prevent osteoporosis, enhance immunomodulation for rheumatic conditions, and treat depression.
