Lymphedema

Scientists at University of Auckland discovered that insulin-like growth factor (IGF) can stimulate the growth of lymphatic vessels.
The finding was first observed in zebrafish and later confirmed in human lymphatic cells.
Lymphedema occurs when damaged lymphatic vessels cannot properly drain excess fluid, leading to swelling, usually in the arms or legs.
Current treatments manage symptoms (compression therapy, massage), but this discovery could help restore lymphatic function in the future.
More research is needed before this approach can be developed  into a clinical therapy.
