Calcium Exchange in Myocardial Tissue Culture
Calcium (Ca2+) exchange in whole, functional cardiac tissue is complex (Shine et al., 1971). The exchangeable fraction is characterized by a minimum of five phases. These include vascular, interstitial, and cellular components that are not unequivocally separable. Quantitation of contents ascribable to particular morphological loci and fluxes across identifiable membranes is not possible. A unique model that includes the five phases, describes tissue Ca2+ flux, and is capable of being tested experimentally cannot be rigorously defined.
