We previously reported that mutation of the transforming growth factor-beta3 (TGF-beta3) gene caused cleft palate in homozygous null (-/-) mice. TGF-beta3 is normally expressed in the medial edge epithelial (MEE) cells of the palatal shelf. In the present study, we investigated the mechanisms by which TGF-beta3 deletions caused cleft palate in 129 x CF-1(More)
Exogenous addition of neutralising antibody to transforming growth factor-beta 1,2 to cutaneous wounds in adult rodents reduces scarring. Three isoforms of transforming growth factor-beta (1, 2 and 3) have been identified in mammals. We investigated the isoform/isoforms of TGF-beta responsible for cutaneous scarring by: (i) reducing specific endogenous(More)
In man and domestic animals, scarring in the skin after trauma, surgery, burn or sports injury is a major medical problem, often resulting in adverse aesthetics, loss of function, restriction of tissue movement and/or growth and adverse psychological effects. Current treatments are empirical, unreliable and unpredictable: there are no prescription drugs for(More)
Fetal wound healing occurs rapidly, in a regenerative fashion, and without scar formation, by contrast with adult wound healing, where tissue repair results in scar formation which limits tissue function and growth. The extracellular matrix deposited in fetal wounds contains essentially the same structural components as that in the adult wound but there are(More)
To explain the disappearance of medial edge epithelial (MEE) cells during palatal fusion, programmed cell death, epithelial-mesenchymal transformation, and migration of these cells to the oral and nasal epithelia have been proposed. However, MEE cell death has not always been accepted as a mechanism involved in midline epithelial seam disappearance.(More)
Adult wounds heal with scar-tissue formation, whereas fetal wounds heal without scarring and with a lesser inflammatory and cytokine response. We injected the margins of healing dermal wounds in adult rats with neutralising antibody (NA) to transforming growth factor-beta (TGF-beta). All control wounds (irrelevant antibody, or TGF-beta, or no injection)(More)
Duplication of the msh-like homeobox gene of Drosophila may be related to the evolution of the vertebrate head. The murine homologues of this gene, msx 1 and msx 2 are expressed in the developing craniofacial complex including the branchial arches, especially in regions of epithelial-mesenchymal organogenesis including the developing tooth. By performing in(More)
Wound healing in the fetus occurs rapidly, by a regenerative process and without an inflammatory response, resulting in complete restitution of normal tissue function. By contrast, in the adult, wounds heal with scar formation, which may impair function and inhibit further growth. The cellular mechanisms underlying these differing forms of wound healing are(More)
The cellular and molecular mechanisms underlying the effects of aging on human cutaneous wound healing are poorly understood, and the possible role of reproductive hormones in this process has never been investigated. We report that aging in healthy females was associated with a reduced rate of cutaneous wound healing, but an improved quality of scarring(More)
We have studied the expression patterns of the newly isolated homeobox gene, Hox-8 by in situ hybridisation to sections of the developing heads of mouse embryos between E9 and E17.5, and compared them to Hox-7 expression patterns in adjacent sections. This paper concentrates on the interesting expression patterns of Hox-8 during initiation and development(More)
