HW - #5 : 137-176

post on your blog, a summary, an impression, and a question to the section you have read.

1. Summary
   Scientist thought the HeLa cells was so robust that they can be alive everywhere. And they wanted to know the changes of Henriatta’s cells in space. When the first humans went into orbit, HeLa cell was being together so researchers could study the effects of space travel, the nutritional needs of cells in space and how cancerous and non cancerous cells responded differently to zero gravity. They found out by the research that it seemed like all normal cell growing in culture but eventually died or underwent spontaneous transformation and as well as became cancerous.

At that time, Lewis Coriell, renowned cell culturist, published a paper and pointed out one that other researchers hadn’t considered that the HeLa was the contaminant. After his paper was published, Coriell and a few other top tissue culturist met together and talk avout the state of their field which they worried was becoming a disaster. And they founded a reference collection of cells. Their goal was that making a nonprofit federal cell at America Type Cultural Collection. Gey shared HeLa cell other researchers and each of them tested and examined using the cells.
 In 1960, French researchers discovered that when cells were infected with certain viruses in culture, they clumped together and sometimes fused.
 Additionally in 1965 two British scientists created the first human-animal hybrids as well as they found what genes do and how they work. And a British scientist tried to fuse HeLa with chicken cells. And the discovery was right and showed that something in cells regulated genes.
 Soon after a pair of researcher at New York University discovered that human hybrids was unprofessional production.
   In 1966, Stanley Gartler a geneticist announced he’d found a “technical problem” in their field and pointed out the many cells cell were contaminated by HeLa cells.

  Deborah got pregnant when she was in junior in high school. And she also has had second children. However she left her house with her children because her husband caused violence to her.
And Joe was put in prison because he killed ivy and he was changed by reading Koran as well as he changed his name Zakariyya.

2. Impression.

  There are really long story about HeLa cell and Herietta. Especially I realized again science was not absolute but be always available to change.
  And the story of Henrietta's children made me sad. They had a really big pain in their breast. They lost their mom very early and bady. Also, Deborah was gained by her husband and her brother Joe who killed and went to jail.
