FOREWORD. z7 Q# e; v( y" Z: K9 [8 j' E5 k
Stem cell biology is emerging as a field in biology with tremendous therapeutic potential.
6 {# x+ T0 C+ V. ]Making this potential a reality requires an international effort. The recognition) d9 x* M% b! ~/ Z/ l. o2 b
that such a promising yet multifaceted discipline needs fostering led to the establishment
8 y8 L, S4 S/ q1 T* r1 \' [ h8 oof the International Society for Stem Cell Research (ISSCR). Central to the efforts of the
5 s; \, }( y: ?ISSCR is the development of tools to ensure the success of stem cell researchers. What

compendium of protocols in stem cell biology?

have become leaders in the field as a result of developing such techniques. The more

development and lead to the development of therapies. Thus, the availability of quality
