If you have issues with using animal products, then good luck! This is what we use cows for, aside from eating and wearing:

Cell culture laboratories
Bovine serum albumin provides a wide variety of macromolecular proteins, low-molecular-weight nutrients, carrier proteins for water-insoluble components, and other compounds necessary for in vitro growth of cells, such as hormones and attachment factors. Serum adds buffering capacity to the medium and binds or neutralizes toxic components in the growth milieu.
Home and industrial uses
