艾滋病不再是绝症？干细胞移植到底有多神奇【健谈英语】

【头条播报】
US scientists recently revealed that an American woman is believed to have become the first woman, to be cleared of HIV following a novel stem cell transplant treatment. She underwent high-dose chemotherapy that destroyed her blood cells, before receiving a transplant of stem cells from a family member to boost her immunity and replenish her blood cell levels. The patient then received stem cells from the umbilical cord blood of a newborn baby who had no relation to her. The cord blood had a specific mutation that makes cells resistant to an HIV infection.
