Why is chapter 23 called "It's Alive"?

The chapter is called "It's Alive" because this is when Henrietta's family finally finds out about her cells still being alive, but still don't know much about them. I feel like the title is a homage to the 1931 film Frankenstein. The title alludes to in my opinion the fact that the cells are still alive all this time and like in the 1931 film the Lack's family will get a surprise like Dr. Frankenstein.
