- With reference to the latest developments in stem cell research, consider the following statements: 1. The only source of human stem cells are the embryos at blastocyst stage 2. The stem cells can be derived a without causing destruction to blastocysts 3. The stem cells can regenerate themselves in vitro virtually forever 4. Indian research centres also created a few cell lines which can be developed into many types of tissues Which of these statements are correct?
- The stem cells can be derived a without causing destruction to blastocysts: At the time, the standard method for deriving human embryonic stem cell lines involved the destruction of the blastocyst. Research into non-destructive methods (like taking a single cell from an 8-cell stage embryo or using altered nuclear transfer/parthenogenesis) was in nascent stages or controversial. While possible in theory or under development, it wasn't the established primary method, making this statement potentially incorrect in a general context. 3. The stem cells can regenerate themselves in vitro virtually forever: Embryonic stem cells possess the property of self-renewal and can proliferate extensively in culture under appropriate conditions, maintaining their pluripotency. While "virtually forever" might be a slight exaggeration, indefinite proliferation potential in culture is a key characteristic. 4. Indian research centres also created a few cell lines which can be developed into many types of tissues: India has had active stem cell research programs. Establishing human embryonic stem cell lines and demonstrating their pluripotency (ability to differentiate into multiple cell types/tissues) was a goal pursued by research labs worldwide, including in India, in the early 2000s. It is plausible that Indian centres had achieved this or were close to it. 172. The world’s first test-tube baby, Louise Brown, was born under the pioneering work of Dr. Robert Edwards.
