An essential structural feature of fluid-secreting epithelial tissues is the presence of tight junctions. To develop a tissue-engineered organ capable of fluid secretion, the cellular component must establish these structures. As part of efforts to create an engineered artificial salivary gland, we have examined the ability of a candidate allogeneic graft cell line, HSG, to produce several key tight junction proteins, as well as to exhibit functional activities consistent with effective tight junction strand formation. In contrast to results obtained with a control kidney cell line, MDCK-II, HSG cells were unable to synthesize four important tight junction-associated proteins: ZO-1, occludin, claudin-1, and claudin-2. In addition, unlike MDCK-II cells, HSG cell monolayers could not restrict paracellular permeability. HSG cells were, thus, unable to generate significant transepithelial electrical resistance or serve as an effective barrier to osmotically imposed fluid movement. Furthermore, these two functional activities could not be reconstituted via the stable transfection of HSG cells with cDNAs encoding either claudin-1 or claudin-2. We conclude that because of their inability to form tight junctions, HSG cells are unsuitable for use as an allogeneic graft cell in an artificial salivary fluid secretory device. These studies also emphasize the importance of graft cell selection in artificial organ development, as certain required characteristics may be difficult to reengineer.

Establishment of an oriP/EBNA1-based episomal vector transcribing human genomic beta-globin in cultured murine fibroblasts.

A novel oriP/EBNA1-based episomal vector has been constructed that persists episomally in cultured murine fibroblasts. The vector, pBH148, is equipped with the entire 185-kb human beta-globin gene locus. After amplification in bacteria, column-purified episomal pBH148 was transfected into both cultured EBNA1-expressing human D98/Raji positive control fusion cells (DRpBH148) and cultured EBNA1-negative murine fibroblast cells (A9pBH148). Cell cultures were maintained concurrently with and without hygromycin selection for a period of 3 months. We show long-term stable episome maintenance of the full-size 200-kb circular double-stranded pBH148 in both the DRpBH148 cultures and the A9pBH148 cultures, regardless of selective pressure by agarose gel electrophoresis and Southern blot. EBNA1 transgene was detected by PCR in all transfected cultures. In addition, we were able to detect correctly spliced human beta-globin mRNA by RT-PCR in all transfected late-passage DRpBH148 and A9pBH148 cell cultures. These findings illustrate that this oriP/EBNA1-based episomal vector is stable in a previously nonpermissive murine cell line and is a potential vector for human gene therapy.

Lentivirus-mediated gene transfer into hematopoietic repopulating cells in baboons.

Efficient transduction of hematopoietic stem cells is a prerequisite for successful hematopoietic stem cell gene therapy. Oncoretroviral vectors are the most widely used vectors for hematopoietic gene therapy studies. However, these vectors require cell division, and thus efficient transduction of quiescent stem cells has been difficult to achieve. Lentiviral vectors can transduce non-dividing cells and therefore may be more efficient in transducing quiescent hematopoietic stem cells. We have used a competitive repopulation assay in the baboon to compare transduction of hematopoietic repopulating cells by lentiviral and oncoretroviral vectors. Baboon CD34-enriched marrow cells were transduced in the presence or absence of multiple hematopoietic growth factors using a short, 2-day, transduction protocol. Here, we show that efficient lentiviral transduction of hematopoietic repopulating cells was only achieved when cells were transduced in the presence of multiple growth factors. Using these conditions, up to 8.6% of hematopoietic repopulating cells were genetically modified by the lentiviral vector more than 1 year after transplant. Interestingly, the number of lentivirally marked cells increased over time in three of four animals. In conclusion, these results suggest that lentiviral vectors are able to tranduce multilineage hematopoietic stem cells, and thus, may provide an alternative vector system for clinical stem cell gene therapy applications.

Institute of Biotechnology, Swiss Federal Institute of Technology, ETH Zurich, CH-8093 Zurich, Switzerland.
The novel macrolide-inducible and -repressible mammalian gene regulation systems (E.REX) have been cloned into a variety of sophisticated expression configurations including (1) multi-purpose expression vectors, (2) pTRIDENT-based artificial operons, (3) dual-regulated expression strategies for independent control of two different transgenes, (4) autoregulated vectors for one-step installation of adjustable multigene expression, and (5) oncoretroviral and lentiviral plasmids for transduction of macrolide-, streptogramin- and tetracycline-dependent transactivators and production of cell lines supporting independent control of three different transgenes. This vector portfolio represents a construction kit-like toolbox for efficient installation of adjustable gene expression responsive to clinically licensed antibiotics and enables the design of multiregulated multigene metabolic engineering strategies required for biopharmaceutical manufacturing, gene therapy, and tissue engineering. 2002 Wiley Periodicals, Inc.

No understanding, and there is no solution. Of course, none of these approaches are perfect for all hair loss problems, especially due to the heterogeneity of the causes underlying hair losses. Most of chemical drugs and hair transplantation surgeries are accompanied by undesirable side effects.
DreamPharm offers Hair Million (have you heard?) to help treat hair loss. Although there is no science behind this claim, numerous anecdotal cases have demonstrated that this herbal formula based on traditional Chinese herbs actually works. It is not yet understood how Hair Million can stop hair loss and promote hair growth. No scientific research or placebo controlled clinical analysis has been performed on these herbs. Lack of scientific and clinical research is not uncommon in herbal arena. Nonetheless, there are two merits in this hair restoration herbal formula: Firstly, Hair Million is relatively inexpensive, and secondly, it is made of edible herbs that are known to be safe when consumed in regular quantities. Propecia is a clinically tested prescription medication.

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.
DHEA dietary supplements are used for
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.
