Nortis, a Seattle-area startup founded in 2011 that markets “organ-on-a-chip” technology, has raised $6 million, according to an SEC filing.

The company’s microfluidic chips foster the growth of human cells in ways that resemble organs, and have been used to create kidney, liver, blood vessel, heart, intestine, and tumor models for researchers.

Nortis has previously received backing from the Bill & Melinda Gates Foundation and collaborated on a project to send a kidney chip into space. Its chips are used in research studies. The company spun out of VisionGate and is led by Thomas Neumann, a former exec at VisionGate.

We’ve reached out to the company for more details about the new funding and will update if we hear back.
