In terms of veganism. Some will, some won't. It depends. Some vegans will be against any suffering and might consider the harvesting of cells from the progenitor animal. Others may be against this due to a lack of consent (from the animal). Others might consider the initial harvesting as harmless, e.g. the cells/DNA might have naturally shed. There's quite a spectrum of vegans out there.
