Abstract: A tissue culture plate material retainer system includes a culture material retainer having a retainer ring with a retainer ring gap to enable the retainer ring to be compressed for insertion into a culture plate well and a plurality of retainer legs that extend down from the retainer ring to hold culture material down in the well of the culture plate in or under a culture medium. A culture material retainer has a retainer ring that extends along a top and a plurality of retainer legs that extend down from the retainer ring. The retainer ring extends from a first end to a second end forming a retainer ring gap that enables the retainer ring and culture material retainer to collapse or flex radially inward for insertion into a wall.

Abstract: Acellular amnion derived therapeutic compositions are described having a number of various compositional embodiments. An acellular amnion derived therapeutic composition has essentially no live or active amniotic cells. The amniotic cells may be destroyed and the cells and cell debris may be removed from the acellular amnion derived therapeutic composition. An acellular amnion derived therapeutic composition may comprise micronized placental tissue particles, and/or amniotic fluid. An acellular amnion derived therapeutic composition may be a dispersion of micronized amniotic membrane combined with a fluid, such as plasma, saline, amniotic fluid, combinations thereof and the like. An acellular amnion derived therapeutic composition may be combined with a matrix component to form a composite. An acellular amnion derived therapeutic composition may be used in conjunction with a composition comprising viable cells, such as stem cells.

Abstract: A method for making an acellular human amnion-derived composition configured for therapeutic use is disclosed and generally includes the steps: obtaining amniotic membrane tissue; testing the amniotic membrane tissue for pathogens; washing the amniotic membrane tissue; manually removing blood-containing chorion tissue from the amniotic membrane tissue decellularizing the amniotic membrane tissue with xeno-free enzymes; collecting amniotic cells from the decellularized amniotic membrane tissue; seeding the amniotic cells for culture into xeno-free media formulated for mesenchymal stem cells; growing the amniotic cells to a specified confluency; collecting conditioned media; and freezing the collected conditioned media; wherein the method further includes irradiating the conditioned media.
