Brain tumors may originate with neural stem cells, researchers say

.... Strategies that focus only on treating localized lesions would not be sufficient to eradicate tumor cells because these cells may eventually be replenished from the cell pool within the subventricular zone, the researchers said. They also determined that inactivation of both p53 and NF1 is sufficient to in...

Failure to dispose of unneeded cells during development linked to cancer

...Hospital and colleagues found that all the genetic lesions associated with inherited pheochromocytomas result in a reduction of programmed cell death, called apoptosis, during development. The researchers show that mutations in each of the disparate genes that cause familial pheochromocytoma, NF1, c-RET, SDH...

Tissue engineered from fetal skin cells could treat paediatric burns

...laced fetal skin cell constructs on the children's lesions and bandaged them. They changed their dressings every 3-4 days for 3 weeks. The researchers found that all the children had their wounds closed at just over 2 weeks and no child needed traditional grafting because the fetal constructs closed their wo...

Prostate cancer uses Wnt signaling proteins to promote growth of bone tumors
