4. anonymized commercially available macrophage cell lines
   
5. anonymized cell lines, cell products, or material purified from cells, tumor cells or cultured cell lines

Examples of material that do require CPHS approval, include but are not limited to:

1. embryonic or fetal tissue, including the placenta, amniotic fluid, umbilical cord blood and stem cells
   
2. tumor tissue
   
3. tissues from individual donors
   
4. material from cadavers
   
5. diagnostic specimens collected for or being used for research purposes
