Dermal papilla cells (DPCs) in the mammalian hair follicle have been shown to develop hair follicles through epithelial-mesenchymal interactions. A cell therapy to regenerate human hair is theoretically possible by expanding autologous human DPCs and transplanting them into bald skin, though much remains to be overcome before clinical success. In this study, we compared gene signatures of human...

An important consideration in interpreting indices of gene expression in human bone is relating mRNA levels to functional endpoints such as bone architecture. In the present study, a method was developed for quantitative measurement of gene expression and bone morphology in the same specimen. Three-dimensional images of iliac crest bone biopsies from healthy premenopausal women were obtained us...

During pregnancy, insulin-like growth factors (IGFs) are important for growth of fetal and maternal tissues. One of the IGF binding proteins, IGFBP-1, is thought to regulate their activity within the local environment of the placenta. IGFBP-1 usually exists as a phosphorylated, high affinity species, which sequesters IGFs, thereby inhibiting their actions. This study has investigated the mechan...

The D98/AH-2 cell line (a subline of HeLa) expresses a form of alkaline phosphatase (ALP) which closely resembles the adult and fetal intestinal forms of ALP. To characterize this ectopic form of ALP, four monoclonal antibodies were raised against D98/AH-2 ALP, and their binding with ALPs from D98/AH-2 cells, placenta, fetal intestine (meconium), adult intestine, and liver was compared using an...

The D 9 8 / A H 2 cell line (a subline of HeLa) expresses a form of alkaline phosphatase (ALP) which closely resembles the adult and fetal intestinal forms of ALP. To character ize this ectopic form of ALP, four monocIonal antibodies were raised against D 9 8 / A H 2 ALP, and their binding with ALPs from D 9 8 / AH-2 cells, placenta, fetal intestine (meconium), adult intestine, and liver was co...

Throughout in utero development, the placenta plays a key role in controlling growth and development. The placenta acts not only as a gatekeeper of nutrient and waste exchange between mother and developing fetus, but also as a regulator of the intrauterine environment. Its functions can be influenced by the environment encountered throughout pregnancy, thereby altering the appropriate genetic p...

objective: different techniques have been suggested for the repair of bone defects at the injured sites. use of biomembranes, or application of plasma rich in growth factor (prgf) at the site of proliferation of osteoblasts are among the suggested techniques. the current study aimed to compare the biocompatibility of human periodontal ligament fibroblasts (hplf) cultured on hypro-sorb f, perica...

alkaline phosphatase (ortho phosphate, monoester hydrolase phosphoinositide e. c. 3.1.3.1) is a non-specific metalloproteinase enzyme that is located inside periplasmic space of bacteria. this enzyme is used to measure freshwater sediment in genetic engineering for cleaning water. isolation and molecular identification of the bacteria producing alkaline phosphatase and comparison of its product...

introduction: hydatid cyst disease is caused by the protoscolices of echinococcus granulosus. alkaline phosphatase (alp) enzyme is required for metabolism, physiology, immunology, and nutrients absorption in parasite. the aim of this study was to compare the level of alp activity (as a pathological biomarker) in hydatid cyst protoscolices (hcp) with that of sheep liver tissue and to determine t...
