Passage B: Questions 36-40        There've been advances in regenerative medicine research that could improve the treatment ofthose with blood cancers such as leukemia, Iymphoma, and myeloma. The new research bringshope that there will one day be the ability to create customized human stem cells that can formblood. The idea is that doctors would take a patient's own cells to make "hematopoietic" stem cells.The patient's mature cells would be "reprogrammed"' so that they can become any kind of humancells. If this can be done, it would change what patients with blood cancers would have to gothrough. Currently, patients with blood cancers have to undergo strong radiation and chemotherapytreatments to kill the cancer cells. But along with getting rid of the cancer cells, the treatments alsodestroy their white blood cells. As a result, patients often need bone-marrow transplants, which areusually lengthy and often unsuccessful. The reprogrammed cells, however, would not get rejectedby a patient's body and would eventually be able to recreate heal thy new blood cells. If this everworks out, it'll be like getting the holy grail in this field of research.
【題組】36. What do some people equate the possibility of customizing stem cells to?
(A)Obtaining something extremely difficult.
