In a first, the Weizmann Institute’s Prof. Jacob Hanna and his group have grown mouse embryos in an artificial uterus. The feat allows scientists to study the early stages of development, with potential implications that include understanding why implantations fail and the gestational conditions behind developmental disorders, as well as reduced need for laboratory animals.
Developing frog embryo brains damaged by nicotine exposure can be repaired by treatment with ionoceutical drugs that restore bioelectric patterns in the embryo, followed by repair of normal anatomy and brain function. The research suggests therapeutic drugs may be used to help repair birth defects.
Chirality is a type of asymmetry where something can’t overlap with its mirror image, like our hands. Michael Ostap, Ph.D., is researching what causes chirality on a molecular level to better understand embryonic development and how it can go wrong.
