  • Their results showed that delaying transplantation increased cell proliferation, without increasing apoptosis, consequently leading to increased graft size in the delayed condition. (jneurosci.org)
  • Delayed graft transplantation also led to an increase in donor-derived blood vessels, resulting in a transient improvement of graft vascularization at 4 d after transplantation. (jneurosci.org)
  • The host vessels were more swollen 7 d after transplantation in the no-delay group than in the delayed transplantation group, suggesting that ongoing inflammation was present in the no-delay group. (jneurosci.org)
