particulate can be of the same or different source of extracellular matrix as the sheets so that for example the sheets can be made from sis and the particulate can be from lbm the emulsion gel paste liquid or particulate placed in between the sheets of matrix can be of mixed source of extracellular matrix so that for example an emulsion gel paste liquid or particulate can be a 50 50 mixture of lbm and ubs or essentially any ratio ranging from 1 99 to 99 1 thus the emulsion gel paste liquid or particulate that comprises the composition placed between two sheets of extracellular matrix can be some mixture or ratio of extracellular matrix from one or more tissue sources or it can be from a single tissue source mammalian tissue sources are in general any tissue having an extracellular matrix that can be isolated from a mammal and de cellularized thus for example most mammalian organs are tissue sources the tissue sources can be for example any mammalian tissue including but not limited to the small intestine large intestine stomach lung liver kidney pancreas placenta heart bladder prostate tissue surrounding growing tooth enamel tissue surrounding growing bone and any fetal tissue from any mammalian organ the forms of the extracellular matrices that make up the articles are generally any form of extracellular matrix including forms such as sheets or other forms that result from human manipulation with the extracellular matrix generally the broad categories of forms appear to be liquid semi solid or solid liquid is generally a thin emulsion that is injectable and fluid semi solid is generally a rather thicker.
