Nuclear transplantation in Bombina orientalis and utilization of the Pale mutation as a nuclear marker

The Journal of Experimental Zoology

Abstract

The discoglossid frog, Bombina orientalis, displays many characteristics that make it desirable as a laboratory animal. We report here the first successful transplantation of embryonic nuclei into enucleated eggs of this organism. The participation of the grafted nucleus in the development of the transplant embryos was confirmed with the use of a genetic marker, the Pale mutation. Frogs homozygous for this recessive gene are much lighter in appearance than the wild-type animals. The use of this trait in appropriate experiments demonstrated that nuclear transplantation in B. orientalis provides embryos whose nuclei may be reliably interpreted as being derived from the injected nucleus.

Allogenic & Autologous Therapies

Allogenic therapies are generated in large batches from unrelated donor tissues such as bone marrow. In contrast, autologous therapies are manufactures as a single lot from the patient being treated. Here is the latest research on allogenic and autologous therapies.

Cell Fate Conversion By mRNA

mRNA-based technology is being studied as a potential technology that could be used to reprogram cell fate. This technique provides the potential to generate safe reprogrammed cells that can be used for clinical applications. Here is the latest research on cell fate conversion by mRNA.
