A team of scientist from the University of Gothenburg has manage to grow new veins for a 10 - year - old miss using her own stem cells — and then , in a medical first , successfully engraft them into her consistence .
The teamexplain in the Lancetthat the missy had a blocked hepatic portal vein — the blood vas which takes blood off from the gut and to the liver . The condition often results in intragroup bleeding , and the usual approach is to replace it with a discussion section of healthy nervure from elsewhere in the physical structure .
Instead , the Swedish squad decided to grow a vein for her using bone kernel stem cells . They take on a department of vein from a conferrer consistency , stripped it of its cells , then seeded the remaining underground with the girl ’s stem cells . The outcome was a 4 - in long vein surgical incision .
Since it was used to replace her hepatic portal vein the little girl has made a rapid recovery . While the procedure is only now being reported , the OR occurred over a year ago and , since , she has turn three column inch and put on 10 Egyptian pound . She now even run for long walks and does gymnastics . Martin Birchall and George Hamilton , two doctors write about the subprogram in the Lancet , explain :
“ The young girlfriend in this write up was spare the trauma of having nervure harvested from the deep neck or leg with the associated risk of lower tree branch disorder , and avoided the motivation for a liver or multivisceral organ transplant … [ S]he has an better exercise tolerance and evidence of improved cognition . Thus , in a long - full term economic analysis , the substantial price for a one - off , personalised discussion can be justify . However penetrating pressures on health systems mean that this disceptation might be impractical in larger numbers of patients . ”
Because the trunk often rejects blood vessels that come directly from other patients , the two options are invasive operating theater or , now , regenerative medicine like this . distinctly , the second option is better for affected role , but it is expensive . If the price can be driven down , there ’s no grounds such techniques should n’t become common topographic point in the future . [ The LancetviaThe Guardian ]
