Cell and molecular biology are among the topics that have led to application of technology. Problems arise when learners lack understanding concepts or even frequent misconceptions due many abstract concepts. This study aims determine level student through a resume in form portfolio. The research method used descriptive approach. population is students Biology Education program which has taken ...

human mesenchymal stem cells (hmscs), which also called mesenchymal stromal cells, are multipotent stem cell. human mscs typically are positive for the surface markers cd44, cd73, cd90, cd105, cd106, and also negative for hematopoietic markers cd34 and cd45.these cells can be isolated from postnatal bone marrow, adipose tissue, placenta, and scalp tissue, as well as from various fetal tissues. ...

introduction: stem cell biology has been the subject of much recent discussion. embryonic stem (es) cells, derived from the inner cell mass of the blastocyst stage of early mammalian embryos are expected to become a powerful tool in future regenerative medicine and developmental biology due to their capacity of self-renewal and pluripotency. in the present study, the ultrastructural development...
