Defective in vitro growth of the hemopoietic progenitor cells in the acquired immunodeficiency syndrome.

TRANSFORMING GROWTH FACTOR β2 UP-REGULATES GM-CSF GENE IN HUMAN BLADDER CARCINOMA CELL LINE HTB 5637

Transforming growth factor betas are multifunctional polypeptides in the cytokine superfamily. They have a growth inhibitory role on hemopoietic progenitor cells in semisolid colony assay as well as in long-term bone-marrow culture. TGF - β2 represses stromal cells, stem cell factor gene transcription, and decreases the stability of c-kit transcripts in hemopoietic cells. TGF-β also modulat...

Endothelial Progenitor Cell Dysfunction in Polycystic Ovary Syndrome: Implications for The Genesis of Cardiovascular Diseases

Blastema from rabbit ear contains progenitor cells comparable to marrow derived mesenchymal stem cells

Rabbits have the capacity to regenerate holes in their ears by forming a blastema, a tissue that is made up of a group of undifferentiated cells. The purpose of the present study was to isolate and characterize blastema progenitor cells and compare them with marrow mesenchymal stem cells (MSCs). Five New Zealand white male rabbits were used in the present study. A 2-mm hole was created in the a...

The knowledge and attitude of Turkish pre-clinic and clinic dental students towards the dental treatment of patients with human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS)

BACKGROUND AND AIM: Acquired immunodeficiency syndrome (AIDS) is one of the most stigmatised diseases which leads the individuals to feel alone with the social and economic anxiety. The aim of the present study was to evaluate the knowledge and attitude of dental undergraduate students about human immunodeficiency virus (HIV)/AIDS. METHODS</strong...

Isolation and Characterization of the Progenitor Cells From the Blastema Tissue Formed at Experimentally-Created Rabbit Ear Hole

  Objective(s): Throughout evolution, mammalians have increasingly lost their ability to regenerate structures however rabbits are exceptional since they develop a blastema in their ear wound for regeneration purposes. Blastema consists of a group of undifferentiated cells capable of dividing and differentiating into the ear tissue. The objective of the present study is to isolate, culture expa...
