Project Overview

Developmental Biology (Prof. R. Huang)

The research of my group focuses on cellular and molecular mechanisms that underlie embryonic development. We use the chick embryo as a vertebrate model organism, which is easy to manipulate using classical and molecular approaches. We are particularly interested in the signals that control cell fate decisions. For instance, we are investigating how somite cells give rise to skeletal muscle, cartilage, bone and tendon.

Current Research Projects

1.      Development and regeneration of the intervertebral disc

By linking the powerful fate mapping techniques of chick-quail chimeras to tissue manipulation protocols and molecular biological techniques, we determined the fate of the somitocoel cells, a population of mesenchymal cells located in the centre of somites and showed that they contribute to the Anulus fibrosus of the intervertebral disc. We termed the somite compartment formed by somitocoele cells as the arthrotome.  We are going to analyze the signalling network controlling the development of the intervertebral disc.


2.      Development of skeletal muscle satellite cells

Recently, we have shown that the somatopleure adjacent to the occipital somites has a myogenic potential and contributes to the superficial neck muscles and a shoulder girdle muscle. Furthermore, these muscles develop according to a myogenic repertoire, which is specific for head muscles. We are now investigating the developmental properties and regenerative competence of skeletal muscle satellite cells derived from somatopleure.
