- still attached to stromal network of BM
- not attached to stromal network but still in BM
- still attached to stromal network of BM: Pro-B cells
- not attached to stromal network but still in BM: Pre-B cells
- distinguished by the apperance of complete IgM molecules
- no IgD
Immature B cells
cells that have IgM & IgD in surface for attachment of antigen
Mature B cells
