Kiaa1867 (human Kirre, hKirre) has a critical role in brain development and/or maintenance of the glomerular slit diaphragm in kidneys. Murine homolog of this gene, mKirre expressed in OP9 and AFT024 cells could support hematopoietic stem cells/hematopoietic progenitor cells (HSC/HPC) expansion in vitro. HKirre is also expressed in human FBMOB-hTERT cell line and fetal liver fibroblast-like cel...

Achillea eriophora D.C. (Asteraceae), an endemic species in Iran, is used extensively in Iranian folk medicine to treat various ailments, including gastrointestinal disorders, skin inflammations and wound healing. The present study was aimed to investigate the effects of the methanolic extract of  A. eriophora leaves on the stimulation of human fibroblast cell proliferation and migration as two ...

Antigens and receptors that are highly expressed on tumor stromal cells, such as fibroblast activation protein (FAP), are attractive targets for antibody-based therapies because the supporting stroma and vessel network is essential for a solid neoplasm to grow beyond a size of 1-2 mm. The in vivo characterization of antibodies targeting human stromal or vessel antigens is hindered by the lack o...

BACKGROUND Human immunodeficiency virus (HIV)-infected (HIV+) men are more susceptible to sexually transmitted infections, and may be superinfected by HIV. We hypothesized that HIV induces immune alterations in the foreskin that may impact the subsequent acquisition/clearance of genital coinfections. METHODS Foreskin tissue and blood were obtained from 70 HIV-uninfected and 20 HIV+ men underg...

background  isolation of adipose tissue mesenchymal stem cells (mscs) with current enzymatic methods has some limitations. for example, it is costly and time-consuming and results in a heterogeneous cell population that making compromise proliferation and differentiation of mscs. also, it is accompanied with the increased risk of culture contaminations because of several handling steps.in this ...

objective: as a biological tissue material, amniotic membrane (am) has low immunogenicity and to date has been widely adopted in clinical practice. however, some features such as low biomechanical consistency and rapid biodegradation is limited the application of am. therefore, in this study, we fabricated a novel three-dimensional (3d) spongy scaffold made of the extracellular matrix (ecm) of ...

The current study was to investigate whether embryo or fetal fibroblast cells treated with 5-aza-2’-deoxyctidine (5-aza-dC) have a positive effect on the in vitro development of porcine parthenogenetic and cloned embryos. To this end, porcine fetal fibroblast cells were treated with different concentrations (5 nM, 50 nM and 500 nM) of 5-aza-dC for different exposure times (1, 6 and 20 hours), t...

OBJECTIVE To investigate the morphology of cultured fibroblasts derived from abnormal scars and compare it to those of human normal skin. METHODS This study was carried out in the Surgical Clinic, Faculty of Medicine, King Abdul-Aziz University, Jeddah, Kingdom of Saudi Arabia between December 2008 and March 2010. Fifty-two samples of hypertrophic and keloid scar were collected. An in vitro s...

INTRODUCTION This study aimed to compare the cytotoxicity of MTA Fillapex, AH-26 and Apatite root canal sealers at different times after mixing. METHODS AND MATERIALS In this in vitro study, MTA Fillapex, AH-26 and Apatite root canal sealer were spilled uniformly by 40 µm mesh in a 96-well plate. Then, human fetal foreskin fibroblast cell line (HFFF2) were added to each sealer cell culture me...

Background & Aims: Induced pluripotent stem cells (iPSCs) have the capability to undergo unlimited selfrenewal and differentiation into all cell types in the body. These cells are artificially derived from a nonpluripotent cell, typically human dermal fibroblasts (HDFs). The study of cytogenetic stability of these cells, in order to use iPS cells and apply studies in therapeutic applications, i...
