   Stem cells are relatively unspecialized cells that have the ability to renew themselves and produce a variety of specialized cells after division without limit, as long as animal is still alive. These criteria were directed to produce many types of differentiated cells to repair damage in the body (Watt , 2011). It is the original cell of an organism that has the ability to develop into many different types of cells in the body.

   This study was constructed to investigate hyperprolactinemia related infertility through  a biochemical and molecular base   associated with single nucleotide polymorphism (SNP) at prolactin gene and prolactin receptor gene in hyperprolactinemic patients. The study included one hundred fifty blood samples from patients suffering hyperprolactinemia and infertility during the period from March

Many soil samples were collected from different places and screened for PHA production by Sudan Black B stain. Twenty isolates had a positive result for Suddan Black B stain. The results were confirmed by staining the viable colonies with the selective stain Nile Red; three isolates gave positive results. One isolate with a more pink fluorescent with Nile Red stain was selected for the present study.
