In healthy individuals, skin has a remarkable capacity for regeneration following damage, but age and
diabetes-related vascular problems often lead to chronic non-healing wounds for many thousands of
UK patients. Therefore, there is a need for new therapeutic approaches to treat these problematic
wounds. In recent years, mesenchymal stem cells (MSCs) have been shown to assist cutaneous
wound healing by accelerating re-epithelialisation and reducing scarring. My research aim was to
investigate the role of MSCs in a wound environment using tissue-engineered skin (TE skin) as an in
vitro 3D wound model. TE skin is skin that has been reconstructed from human dermis, fibroblasts and
keratinocytes, such that it resembles ex-vivo skin.
Firstly, a method for delivering MSCs to patients, that would be convenient and safe for a clinician to
use, was derived. Plasma polymerisation was used to functionalise the surface of medical grade
silicone with acrylic acid to make its surface favourable for MSC attachment. MSCs cultured on these
'carrier' surfaces retained their viability and phenotype, and could migrate to human dermis from the
carrier’s surface with great efficiency upon contact with model wound beds. Once transferred, the
MSCs remained viable.
Secondly, a reproducible wound-healing model was developed from TE skin and the ability of MSCs to
bring about wound healing in the model was investigated. MSCs were introduced to wounded TE skin,
and Optical Coherence Tomography (OCT) was employed to non-invasively image the wound area
over the course of healing. OCT is the light source equivalent of ultrasound, providing a much higher
lateral and axial resolution than the latter. Samples containing MSCs did not heal faster than controls;
however the rate of re-epithelialisation was improved. Restoration of the skin's barrier occurred
several days earlier in the presence of MSCs, and this event could be detected by OCT. This
observation was associated with increased levels of hepatocyte growth factor. Therefore, OCT proved
an effective tool to investigate wound healing in vitro, and MSCs may have contributed to wound
healing in a paracrine fashion.
