Research Area

a tissue-slice preparation was developed to study single-cell physiology, secretory function and development of neurosecretory cells, such as the beta cells of the pancreas and pituitary cells. One of the aims of the group is a better understanding of differentiation processes, which eventually may
lead to advances in cellular replacement therapy.
