US Government Allows Stem Cell Tests on Humans

The video discusses Geron Corporation's FDA-approved human trials using embryonic stem cells, marking the first attempt to use these cells in humans. Stem cells can transform into specialized cells, offering potential to replace damaged ones. Geron's trials involve testing on rats, showing significant improvements in locomotion after stem cell injections. The video highlights the unpredictability and time-consuming nature of stem cell research, urging public patience. It also covers the political history of stem cell research funding, noting the Bush administration's restrictions and the Obama administration's efforts to reverse them.

What is the primary goal of Geron's human trials with embryonic stem cells?

• To develop new medications for spinal injuries

• To create new types of stem cells

• To replace diseased or injured cells in humans

• To test the safety of stem cells in animals

In Geron's animal trials, what was the outcome after injecting human embryonic stem cells?

• Permanent improvement in locomotion and body control

• Temporary improvement in motor functions

• Development of new diseases in the animals

• No change in the animals' condition

Why do researchers caution the public about the results of stem cell research?

• Because the research is already complete

• Because the results are always negative

• Because science is unpredictable and takes time

• Because the results are immediate

What was the Bush administration's policy on embryonic stem cell research?

• It restricted federal funding to a few existing stem cell lines

• It encouraged private funding for stem cell research

• It banned all stem cell research

• It allowed unlimited federal funding for all stem cell research

What change did President Obama and Congress aim to implement regarding stem cell research?

• To limit research to adult stem cells only

• To increase restrictions on stem cell research

• To reverse restrictions on federal funding for stem cell research

• To ban all forms of stem cell research
