X-Message-Number: 24163 From: Date: Fri, 28 May 2004 21:28:42 EDT Subject: cell freezing protocols (Basie >About 50 percent to 70 percent of sperm dies during thawing, We freeze lots of fibroblasts and endothelial cells in the lab using 1960s methods that kill half the cells. That doesn't mean it can't be done better; it just means no one cares much about individual sperm or fibroblasts. Look up how they freeze the EGGS and you'll see more encouraging statistics. -Bill Content-Type: text/html; charset="US-ASCII" [ AUTOMATICALLY SKIPPING HTML ENCODING! ] Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=24163
