Abstract

A method for isolation, enrichment and co-culture of foetal polymix involving two or more components of mesenchymal stem cells derived from, but not limited to, placenta, amnion, amniotic fluid, chorion and umbilical cord and/or other products of conception under hypoxic or otherwise and/or normoxic/general conditions for treatment of a plurality of disorders ranging from congenital to degenerative to developmental to malignant disorders and diseases prior to therapeutic administration.

incubating the seeded isolated mesenchymal stem cells until the seeded isolated mesenchymal stem cells reach 70-80% confluence,

wherein the MSCs from an umbilical cord are isolated and enriched by a process comprising of:

subjecting a processed umbilical cord to an enzymatic digestion with collagenase and hyaluronidase to form a mixture;

incubating the mixture containing the processed umbilical cord, collagenase, and hyaluronidase with gentle agitation;

adding trypsin to the agitated mixture and then incubating to obtain a digested suspension;

isolating cells containing MSCs from the washing solution;

seeding isolated MSCs with DMEM into a second culture vessel; and

incubating the seeded isolated MSCs until the seeded isolated MSCs reach 70-80% confluence.

27 . The method of claim 26 , further comprising wherein the foetal polymix composition is formulated into an injectable composition.

28 . The method of claim 26 , further comprising wherein the foetal polymix composition is formulated to be suitable for administering via an intravenous route, an intrathecal route, an intra-articular route, an intramuscular route, a derma roller, a mesogun, a local route, a periorbital route, an intravitreal route, or a retrobular route.

29 . The method of claim 26 , further comprising wherein the foetal polymix composition is formulated to be suitable for treating disorders and diseases.

30 . A method making a foetal polymix composition, the method comprising:

isolating mesenchymal stem cells (MSCs) from two separate sources, wherein the two sources are placenta and umbilical cord tissue;

enriching the MSCs from each source separately; and

co-culturing the enriched MSCs from each source together in a culture medium under hypoxic conditions, wherein the hypoxic conditions comprise incubation in a carbon dioxide incubator at 37° C. with 1% oxygen concentration, and with a remaining concentration containing carbon dioxide and nitrogen,

wherein the MSCs from placenta are isolated and enriched by a process comprising of:

collecting a fetal decidua's placental tissue from placenta;

washing the fetal decidua's placental tissue with a phosphate buffer solution (PBS);

digesting the fetal decidua's placental tissue with collagenase;

separating cells by centrifuging a mixture of the fetal decidua's placental tissue and collagenase over a Ficoll-Hypaque separation medium to obtain separated cells;

re-suspending the separated cells for culture in L-Dulbecco's Modified Eagle's Medium (LDMEM) supplemented with fetal bovine serum, basic fibroblast growth factor, L-glutamine, and at least one antibiotic;

seeding cells from the LDMEM into a first culture vessel;

removing non-adherent cells from the first culture vessel;

harvesting cells from the first culture vessel by adding trypsin and ethylenediaminetetraacetic acid (EDTA); and

passaging the cells,

wherein the MSCs from an umbilical cord are isolated and enriched by a process comprising of:

subjecting a processed umbilical cord to an enzymatic digestion with collagenase and hyaluronidase to form a mixture;

incubating the mixture containing the processed umbilical cord, collagenase, and hyaluronidase with gentle agitation;
