Researchers at the University of Pittsburgh School of Medicine used porcine extracellular matrix (ECM) to induce stem cells into muscle cells. The study found that transplanting these cells can regenerate muscles lost due to accidental injury and mus...
2020-08-17Australian researchers at the University of New South Wales School of Medicine in Australia are using a gene therapy called electrical gene delivery, which uses an electric field to restrict gene delivery to cochlear electrodes. This study provides e...
2020-08-17Researchers at Boston Children\'s Hospital in Boston used a mixture of transcription factors composed of eight gene switches to reprogram the mature blood cells of mice into hematopoietic stem cells (HSC). Reprogrammed cells researchers claim that HS...

2020-08-14Animal research usually involves examining the biological characteristics of animal models of specific species, strains or genders to indirectly infer whether humans or other research targets have similar biological characteristics...
2020-08-14Animal pups born after microinjection need to be analyzed as soon as possible to identify animals that are positive for the transgene. The primary animal that is determined to contain the transgene is called the founder of the transgene. Then, mate t...
