Automated systems and methods for isolating regenerative cells from adipose tissue
View Patent ↗A method of processing an adipose tissue to collect adipose derived regenerative cells is provided, wherein the method comprises providing a vessel comprising a fluid jet mixer; introducing the adipose tissue into the vessel; introducing a buffer solution into the vessel; washing the adipose tissue using the fluid jet mixer; introducing an enzyme solution into the vessel; initiating jet mixing into the vessel comprising the adipose tissue, the enzyme solution, and the buffer solution using the fluid jet mixer to digest the adipose tissue to form a digestion product; phase-separating the digestion product into a digested buoyant fat layer and a non-buoyant aqueous layer; and collecting the non-buoyant aqueous layer comprising the adipose derived regenerative cells. A system of processing an adipose tissue to collect adipose derived regenerative cells is also provided.
1. A mixing vessel for processing an adipose tissue to collect adipose derived regenerative cells, comprising:
at least one inlet port for receiving adipose tissue, a buffer and an enzyme solution;
a centrally located cylinder comprising one or more nozzles configured to generate a high velocity fluid stream, wherein the nozzles are in an upward direction to generate an upward fluid stream and a jet mixing into the vessel to digest adipose tissue and form a digested buoyant fat layer and a non-buoyant aqueous layer comprising adipose derived regenerative cells;
at least one outlet port comprising a filter unit, wherein the filter unit allows to pass the non-buoyant aqueous layer comprising adipose derived regenerative cells,
wherein the cylinder is operably connected to the inlet port and the outlet port.
2. The mixing vessel of claim 1 , wherein the outlet port is operably connected to a pump.
3. A system for isolating regenerative cells from an adipose tissue, comprising:
a mixing vessel comprising:
at least one inlet port for receiving adipose tissue, a buffer and an enzyme solution;
a centrally located cylinder comprising one or more nozzles configured to generate a high velocity fluid stream, wherein the nozzles are in an upward direction to generate an upward fluid stream and a jet mixing into the vessel to digest adipose tissue and form a digested buoyant fat layer and a non-buoyant aqueous layer comprising adipose derived regenerative cells;
at least one outlet port comprising a filter unit, wherein the filter unit allows to pass the non-buoyant aqueous layer comprising adipose derived regenerative cells,
wherein the cylinder is operably linked to the inlet port and the outlet port;
one or more containers and
one or more fluid circuit tubing is operably connected to the mixing vessel, and to the containers.
4. The system of claim 3 , further comprising a direct current (DC) servo motor.
5. The system of claim 3 , further comprising one or more multi-port valves.
6. The system of claim 3 , wherein the fluid circuit tubing further comprises a filter unit.
7. The system of claim 3 , wherein the centrally located cylinder of the mixing vessel comprises at least four nozzles.
8. The system of claim 3 , wherein the fluid circuit tubing is operably connected to one or more pumps.
9. The system of claim 3 , further comprising a sensor configured to measure mass of the mixing vessel and the containers.
10. The system of claim 3 is enclosed in a chamber, wherein the chamber comprises a temperature controller.
11. The system of claim 10 , wherein the chamber further comprises a fan heater.
