A Simple, Rapid, and Efficient Method for Isolating Mesenchymal Stem Cells from the Entire Umbilical Cord.

Several reports have been published on the isolation, culture, and identification of mesenchymal stem cells (MSCs) from different anatomical regions of the umbilical cord (UC). UC is suitable for standardizing methods of MSC isolation because it is a uniform source with high MSC numbers. Although the UC is considered a medical waste after childbirth, ethical issues for its use must be considered.

Establishment and characterization of Caspian horse fibroblast cell bank in Iran.

Caspian horse, a rare horse breed found in 1965 by Louise Firouz in northern Iran, is a small horse which is reported to be in danger of extinction in its original homeland. There seems to be a great need to prevent extinction of this valuable horse. In this study, 51 fibroblast cell lines from Caspian horse ear marginal tissue were successfully established by sampling 60 horses using primary explant technique.

Prevention and detection of Mycoplasma contamination in cell culture.

One of the main problems in cell culture is mycoplasma infection. It can extensively affect cell physiology and metabolism. As the applications of cell culture increase in research, industrial production and cell therapy, more concerns about mycoplasma contamination and detection will arise.

Proliferation and differentiation of mesenchymal stem cell on collagen sponge reinforced with polypropylene/polyethylene terephthalate blend fibers.

Although tissue-engineered scaffolds made from collagen sponge are suitable for cell infiltrating, easily supplying oxygen and nutrients to cells, and removing the waste products, their mechanical properties are not satisfactory to be used as scaffold materials for tissue engineering applications. To improve mechanical properties of collagen, a novel porous scaffold for bone tissue engineering was prepared with collagen sponge reinforced by polypropylene/polyethylene terephthalate (PP/PET) fibers. Collagen solution (6.

Antibody formation following botulinum toxin type A (Dysport) injection in children with intractable bladder hyper-reflexia.

Objectives: To investigate the pattern of anti-Dysport antibody (ADA) formation after Dysport injection in patients with neuropathic bladder. Antibody formation may lead to failure or allergic reactions in patients undergoing Dysport injection.

Methods: Forty-four children with neuropathic bladder were enrolled and classified into 3 groups: group I, without history of previous injection (n = 8); group II, with history of one or more injections (n = 7); and group III, who had been injected 3-36 months before this study (n = 29).

Transurethral autologous myoblast injection for treatment of urinary incontinence in children with classic bladder exstrophy.

Purpose: The application of autologous myoblasts is an area of active research that may represent an improved alternative for the treatment of urinary incontinence. In this study we investigated the effectiveness of autologous myoblast injection for the treatment of urinary incontinence in children with classic bladder exstrophy.

Materials And Methods: Seven boys and 1 girl with persistent urinary incontinence were entered in the study.

Comparison of two proliferation assays MTT and ltt in immunodeficient patients.

MTT assay is designed for spectrophotometric quantification of cell growth and viability without using the radiactive isotopes. The aim of this study is comparison of LIT and MTT as sensitive poliferation assays in imrnunodeficient patients. 20 immunodeficient and 20 healthy subjects were selected in this study.

The interaction of cytochrome P450 17alpha with NADPH-cytochrome P450 reductase, investigated using chemical modification and MALDI-TOF mass spectrometry.

The lysine residues of guinea pig P450 17alpha were acetylated by acetic anhydride in the absence and presence of NADPH cytochrome P450 reductase (CPR). Eight acetylated peptides were identified in the MALDI-TOF mass spectra of the tryptic fragments from the P450 acetylated without CPR in the limited reaction time of 15 min at ice temperature. The presence of CPR during the acetylation of P450 17alpha prevented double acetylations at K326 and K327 in the J-helix.

Analysis of the interaction between human steroid 21-hydroxylase and various monoclonal antibodies using comparative structural modelling.

Objective: To study the interaction between human steroid 21-hydroxylase (21-OH) and monoclonal antibodies (MAbs) to 21-OH directed to 3 different epitopes recognised by 21-OH autoantibodies characteristic of autoimmune Addison's disease.

Design: Build comparative structural models of 21-OH, 21-OH MAbs and complexes of 21-OH-21-OH MAbs and study the effects of 21-OH MAbs on 21-OH enzyme activity. Then, analyse the relationship between sites important for binding of 21-OH MAbs and 21-OH autoantibodies and sites important for 21-OH enzyme activity.
