1. A cell spray gun comprising:
a tube having a first end, a second end, and a discharge portion proximate to the second end;
a gas source in connection with the first end of the tube and configured to deliver a gas stream from the first end of the tube and out through the second end of the tube;
a support portion configured to receive and secure a container containing a cell suspension;
one hollow needle having a first end and a second end opposite the first end, the first end of the needle removably attached to the container when the container is secured in the support portion, the needle configured for delivery of the cell suspension from the container into the first end of the needle and out through the second end of the needle; and
an actuator configured to push the cell suspension out of the container and out through the second end of the needle,
wherein the second end of the needle is disposed inside the discharge portion of the tube such that the needle and the discharge portion are arranged coaxially and the cell suspension is injected into the gas stream and sprayed from the second end of the tube as suspension droplets.
