Hi Judy,

	Without some notion of what criteria you wish to apply to a
distinction and what instrumentation you have, it is difficult to make a
suggestion.  However, as I am interested in applying confocal to vascular
analysis in the urinary bladder, I can recommend a reasonable starting point
if you haven't already consulted it.

	I suggest that you refer to:

	Methods in Enzymology, vol. 307 (1999), Conn, P.M.(Ed.), Academic
Press, ISBN:  0-12-182208-7
(http://www.apcatalog.com/cgi-bin/AP?ISBN=0121822087&LOCATION=US&FORM=FORM2)
.
	Chapter 15, "Measurement of Vascular Remodeling by Confocal
Microscopy", Arribas, SM, Daly, CJ and McGrath, IC.

Available for more discussion,
