Abstract: The invention relates to the use of hepatocyte and keratinocyte growth factors for controlling the proliferation and motility of corneal cells in vivo and in vitro. It also relates to the use of these factors for maintaining the viability of the corneal cells during or after ocular surgery and during corneal preservation in storage medium prior to transplant. Polymerase chain reaction amplification has demonstrated that corneal epithelial and endothelial cells in vitro and ex vivo corneal epithelium produce messenger RNA coding for hepatocyte growth factor, hepatocyte growth factor receptor, keratinocyte growth factor, and keratinocyte growth factor receptor. Additionally, it was demonstrated that hepatocyte growth factor and keratinocyte growth factor stimulate the proliferation of corneal epithelial cells and corneal endothelial cells in vitro in a dose response manner.

Abstract: Methods for detecting glucagon antagonists through the use of recombinant DNA techniques are provided. Briefly, subsequent to the expression of glucagon analogs within suitable host cells, the analogs are exposed to a glucagon receptor coupled to a response pathway in the presence of native glucagon. A reduction in the stimulation of the response pathway resulting from the binding of the glucagon analog to the glucagon receptor relative to the stimulation of the response pathway by native glucagon alone indicates the presence of a glucagon antagonist. Glucagon antagonists identified and isolated through the methods are also provided.
