cloning and stem cell technology

Private sector development of stem cell technology and therapeutic cloning.

Based on data collected in June 2002, more than 30 biotechnology startup firms in 11 countries are pursuing commercial development of stem cell technology and therapeutic cloning. These firms employ 950-1000 scientists and support staff and spend just under $200 million on research and development each year. The field has the look and feel of a high-tech cottage industry, with about half the st...

Spermatogonial Stem Cell Technology and Regenerative Medicine

Germ cell development begins with the characteristics of the primordial germ cells (PGCs) early in human fetal life. PGCs arise from the proximal epiblast and will replace to the extra embryonic mesoderm during the fourth and fifth week of embryonic development. By the finish of the fifth week to early sixth week, PGCs will embark for a second immigration via the dorsal mesenterium of the gut t...

Islamic perspective on human cloning and stem cell research.

Recent advances in the field of cloning and stem cell research have introduced new hope for treatment of serious diseases. But this promise has been accompanied by enormous questions. Currently, cloning is a matter of public discussion. It is rare that a field of science causes debate and challenge not only among scientists but also among ethicists, religious scholars, governments, and politici...

Stem Cells So far! Stem Cell Therapy Facts and Principles

Stem cells are cells with the ability to divide for indefinite periods and to give rise to specialized cells.  Stem cell therapy has now been emerged as an extraordinary promise to treat a wide range of diseases and conditions.  However, except blood stem cell transfer by bone marrow transplant which has been used as an standard practice for more than 50 years, nearly all of therapeutic potenti...

Advances in Hematopoietic Stem Cell Mobilization and Peripheral Blood Stem Cell Transplantation

Hematopoietic stem/progenitor cells (HSPCs) which give rise to different blood cell types are present within the bone marrow microenvironment, especially in flat bones such as skull, vertebrae, pelvis and chest. Interacting factors such as stromal derived factor-1/CXCR4, very late antigen-4/vascular cell adhesion molecule-1, Lymphocyte function-associated antigen-1/ intercellular adhesion molec...
