B lymphocytes in mouse spleen

If you make a single cell suspension from a mouse spleen by 
mashing it through a mesh or similar, then about 40% of the cells
you get out will be B cells (positive for surface Ig).  See (ahem)
A.H. Fell and P.M. Preston, International Journal for Parasitology
1992, vol. 22 p. 491.  
However, I think there will be some cells left in the spleen tissue
you discard, such as dendritic cells, endothelial cells etc which
are not easily dispersed by mechanical means.  I do not think anyone 
has assessed this, and usually, us immunologists being simple folks,
we chuck them away and regard the lymphocytes as the cells that matter.
I hope this is helpful.
