Lamellipodia and cell migration

Lets get some more knowledge on this. After we get neurogenesis to create new brain cells we can use this to have them move to the correct location. This is really dreaming but I believe in putting the bar high.

Lamellipodia are found primarily in very mobile cells, for example the keratinocytes of fish and frogs, which are involved in the quick repair of wounds, crawling at a speeds of 10-20μm/minute over epithelial surfaces. A lamellipodium separated from the main part of a cell by scratching across the cell with a pipette tip can continue to crawl freely about on its own.

Two different models for how cells move. A) Cytoskeletal model. B) Membrane Flow Model
