TUESDAY, Jan. 9, 2018 — In a potential advance for medical research, scientists say they’ve created the first functioning human muscle from skin cells.

The breakthrough could lead to better genetic or cell-based therapies, as well as furthering investigations into the causes and treatment of muscular disorders, the Duke University team said.

“The prospect of studying rare diseases is especially exciting for us,” Nenad Bursac, professor of biomedical engineering, said in a university news release.

Scientists, who had previously cloned polo ponies, have achieved yet another breakthrough in their work that could lead to the creation of genetically engineered “super-horses” that are faster, stronger and better jumpers than regular horses within two years.

Scientists in Argentina reportedly managed to rewrite the genomes of cloned horses by using a powerful DNA editing technique called CRISPR. They also produced healthy embryos that are now expected to be implanted into a surrogate mother by 2019.

CRISPR, an acronym that stands for Clustered, Regularly Interspaced, Short Palindromic Repeats, is basically a technique in a bacteria’s immune system. When a virus invades a bacterial cell, the CRISPR system captures a piece of the virus’s DNA and slides it into a section of the bacteria’s own DNA, allowing it to detect and destroy the virus as well as similar viruses in future attacks.
