So far the scientists have used this method to spray and grow human fibroblasts and osteoblasts and bovine chondrocytes.

Scientists at the University of Manchester are currently working on a method to use inkjet nozzles to spray human cells. The cells would be the harvested from the patient and then grown to prevent rejection. The cells then can be sprayed in a way to grow to the desired shape and speed healing.
A Stanford University researcher has gotten a preliminary go-ahead to create a mouse with a significant number of human brain cells — as long as the creature behaves like a mouse, not a human.A university ethics committee studied a provocative project that transplants human neurons into the brains of mice where, surprisingly, they settle in and feel right at home. The research team, led by Stanford biologist Irving Weissman, has no immediate plans to build a mouse with an entirely human brain. But it remains a theoretical possibility.
… Weissman says he doesn’t want to build a smarter mouse. Instead, he is creating a furry test tube to learn more about devastating human diseases such as brain cancer, stroke, schizophrenia, Alzheimer’s and Lou Gehrig’s disease — impairments not easily studied in people.

Cyberkinetics Inc has begun government approved human testing of an implant to the human brain:
The System consists of a sensor that is implanted on the motor cortex of the brain and a device that measures and interprets brain signals and translates these signals into useful computer control.
It is hoped that the BrainGate System might someday allow people unable to use their arms or hands to control a computer using their thoughts. The System could potentially be used to help increase the independence of people with disabilities by allowing them to control various devices with their thoughts. Through their control of a personal computer, users of the BrainGate System may be able to control a variety of devices to complete everyday tasks such as composing an email, answering the telephone and controlling a television.
