WebbAn inability to maintain physiologic (in vivo) conditions during this lengthy in vitro culture leads to cellular phenotype drift, ultimately resulting in generation of an undesired tissue. Enhanced tissue generation in vitro will greatly reduce culture times and costs, effecting improved in vitro tissue substitutes which remain true to their original phenotype. radio jazz fm 91WebbChanges in Physiological Dead Space During Deliberate Hypotension Anesthesiology American Society of Anesthesiologists Education November 1964 Changes in Physiological Dead Space During Deliberate Hypotension Vagn F.
