1. A method of expanding adult pancreatic islet-like cell clusters (ICCs), comprising the steps of:
- culturing said ICCs in contact with laminin 5; and
passaging said cultured ICCs in contact with laminin 5 at least once, whereby the number of said cultured ICCs is significantly increased after said passaging.

Abstract
A method of increasing the number of adult pancreatic islet cells available for transplantation by contacting the cells with laminin 5 extracellular matrix. When contacted with the deposited matrix produced by 804G rat bladder carcinoma cells, a 1,500 fold increase in cell number is observed after three passages in culture. Islet cell expansion also occurs when cells are contacted with 804G soluble matrix. The expanded islet cells contain insulin and respond to glucose challenge.
