I’m a postdoc in the Vascular Biology Group at St Vincent’s Institute. The lab is led by Associate Professor Geraldine Mitchell and Dr Kiryu Yap and focusses on tissue engineering techniques for vascular biology.

Current Project: Lab-Grown Skin Flaps for Reconstructive Surgery

In patients with a serious ‘difficult to heal’ wound, due to trauma, diabetes or cancer resection, healthy full-thickness skin is taken from patient donor sites, such as behind the ear, the abdomen or thigh, to cover the wound.

This is called a skin flap, and this procedure creates a secondary deep wound on the patient.

Our research group is investigating lab-made human skin flaps, from human stem cells that incorporate blood vessels and nerves. Eventually the lab-grown skin will be used to cover and promote healing of a patient’s skin wound. With the blood vessels and nerves connected to the patient’s blood vessels and nerves, allowing the patient’s blood to flow through and nourish the lab-grown skin and feel sensation.

A lab-grown skin flap will eliminate harvesting skin flaps from the patient and the second wound site that this creates.

Vascular Biology

As part of the Institute's O'Brien Department, our main research focus is generating human blood vessels for integration in various human tissues grown in the laboratory, including human skin and small pieces of human liver (liver organoids). We also study the structure and function of these lab-generated human tissues.
