A comparative study of human periodontal ligament cells and gingival fibroblasts in vitro.

Both periodontal ligament and gingival tissue are thought to harbor cells with the ability to stimulate periodontal regeneration, i.e., formation of new bone, cementum, and connective tissue attachment. To understand further the role of these cells in the regenerative process, we compared human periodontal ligament cells and gingival fibroblasts, both derived from the same patient, same passage, in vitro. Protein and collagen production was significantly greater in periodontal ligament cells when compared with that of gingival fibroblasts. In addition, periodontal ligament cells had higher alkaline phosphatase levels when compared with those of gingival fibroblasts.

Comments on the clinical application of fibronectin in dentistry.

Several studies have demonstrated that citric acid demineralization of the root surface promotes tissue attachment. Since demineralization exposes collagen to which fibronectin binds, the role of fibronectin in the attachment of cells to the tooth surface has been of considerable interest. It is clear that fibronectin and other cell adhesion proteins can promote cell attachment to the tooth surface; therefore, attempts have been made to utilize these findings in a clinical setting. Using a quantitative ELISA procedure to measure the binding of fibronectin to demineralized bone and tooth, we have found that 1 microgram fibronectin can saturate approximately 1 mg of either demineralized bone or demineralized tooth powder. Since serum contains 300 micrograms fibronectin per mL, the bleeding that occurs during oral surgery should saturate exposed tooth surfaces with amounts of fibronectin adequate for cell adhesion. Thus, exogenous fibronectin would appear to be of little clinical benefit.

OBJECTIVE: To investigate the regulation of perimenstrual MMP-1 expression in human endometrium. DESIGN: In vitro study utilizing epithelial-stromal co-cultures. SETTING: Cell Biology Unit, International Institute of Cellular and Molecular Pathology, and Departments of Pathology and Gynecology, Saint-Luc University Clinics, Louvain University Medical School, Brussels, Belgium. METHODS: Contact-dependent and contact-independent co-cultures were established and resulting MMP-1 gene and protein expression was analyzed by RNase protection assays and soluble-collagen assays. RESULTS: MMP-1 expression in endometrial fibroblasts is markedly stimulated by epithelial cell-conditioned medium. This stimulation can be prevented by antibodies directed against interleukin 1 alpha (IL-1 alpha). Ovarian steroids inhibit MMP-1 production by IL-1 alpha-stimulated fibroblasts in vitro. CONCLUSION: Taken together, our results suggest that epithelium-derived IL-1 alpha is the most important paracrine induced of MMP-1 in endometrial fibroblasts. However, IL-1 alpha-stimulated MMP-1 production in the human endometrium is effectively blocked by ovarian steroids. We believe that this mechanism responsible for the MMP-1 repression that occurs when systemic sex steroid concentrations are high and the MMP-1 production and activity during the perimenstrual phase when estrogen and progesterone concentrations are low.

[Morphological changes in arterial ruptures]

[Article in German]

Scola E.

The historical opinion that the intima layer of a ruptured artery of muscular type could stop bleeding by "rolling in" should be controlled experimentally. Five segments of human femoral/popliteal artery (3-4 cm long) were overstretched until complete rupture occurred. Furthermore a longitudinally split and a partially oblique incised segment were ruptured. As morphological finding a sandclock deformity was observed in the region of rupture. This phenomenon was induced by adventitia layer, which closed the ends of ruptured media layer like a Chinese finger trap. In the longitudinally split segment a transverse rupture of the media layer could be observed, while the fibers of adventitia layer were pulled out when the traction was continued. Neither macroscopical nor microscopical signs could be found for "rolling in" of intima or media layer. The reason for spontaneous hemostasis after arterial rupture is more likely the activation of platelets by collagenous fibers of adventitia layer than "rolling in" of intima or media layer. If there is no finger trap mechanism of adventitia layer like in shot- or stab wounds a massive blood loss must be expected.

Diffusable growth factors induce bladder smooth muscle differentiation.

Bladder smooth muscle differentiation is dependent on the presence of bladder epithelium. Previously, we have shown that direct contact between the epithelium and bladder mesenchyme (BLM) is necessary for this interaction. In this study, we tested the hypothesis that bladder smooth muscle can be induced via diffusable growth factors. Fourteen-day embryonic rat bladders were separated into bladder mesenchyme (prior to smooth muscle differentiation) and epithelium by enzymatic digestion and microdissection. Six in vitro experiments were performed with either direct cellular contact or no contact (1) 14-d embryonic bladder mesenchyme (BLM) alone (control), (Contact) (2) 14-d embryonic bladders intact (control), (3) 14-d embryonic bladder mesenchyme combined with BPH-1 cells (an epithelial prostate cell line) in direct contact, (4) 14-d embryonic bladder mesenchyme with recombined bladder epithelium (BLE) in direct contact, (No Contact) (5) 14-d embryonic bladder mesenchyme with BPH-1 prostatic epithelial cells cocultured in type 1 collagen gel on the bottom of the well, and (6) 14-d embryonic bladder mesenchyme with BPH-1 epithelium cultured in a monolayer on a transwell filter. In each case the bladder tissue was cultured on Millicell-CM 0.4-microm membranes for 7 d in plastic wells using serum free medium. Growth was assessed by observing the size of the bladder organoids in histologic cross section as well as the vertical height obtained in vitro. Immunohistochemical analysis of the tissue explants was performed to assess cellular differentiation with markers for smooth muscle alpha-actin and pancytokeratin to detect epithelial cells. Control (1) bladder mesenchyme grown alone did not exhibit growth or smooth muscle and epithelial differentiation. Contact experiments (2) intact embryonic bladder, (3) embryonic bladder mesenchyme recombined with BPH-1 cells, and (4) embryonic bladder mesenchyme recombined with urothelium each exhibited excellent growth and bladder smooth muscle and epithelial differentiation. Both noncontact experiments (5) and (6) exhibited growth as well as bladder smooth muscle and epithelial differentiation but to a subjectively lesser degree than the contact experiments. Direct contact of the epithelium with bladder mesenchyme provides the optimal environment for growth and smooth muscle differentiation. Smooth muscle growth and differentiation can also occur without direct cell to cell contact and is not specific to urothelium. This data supports the hypothesis that epithelium produces diffusable growth factors that induce bladder smooth muscle.

Hair loss is a problem in modern soceity. Examining the factors of hair growth may shed light on how hair loss might occur. How long can hair grow before it stops growing eventually if it does? Given that the hair growth rate is quite uniform and constant, somewhere between 0.3-0.5 millimeters per day, it's believed that the length of anagen, the growth phase, differs among individuals, and this is the major determinant to the maximum hair length. For some individuals, anagen may last ten years. Of course the length of the anagen is governed by genes, and the genetic background of the individuals. Non-genetic factors such as nutritional condition, weather, seasonal changes (hair may grow a bit faster during winter), taking medications, health condition may of course influence the rate of hair growth as well as The shape of the hair, straight or curly, is dependent on the shape of the follicle. A circular or round hair follicle would generate straight hair, while the follicle with oval or elliptical shapes (in its cross-section) would produce a curly hair.
