The more that is learned about how microfluidic processes control or contribute to cellular change, the sooner science will be able to design a cost-effective medical treatment based on that information. New research on microtubules and blood-vessel organoids augments this.
Recent findings by a team of engineering and medical scientists at Stanford University shed new light on how cell components move around and self-renew. Part of the study’s focus was on the link between microtubules and self-organization. (more…)
Microfluidic engineering advances sustain organoids and fuel the growing stream of organoid uses. As tiny replicas of human organs, organoids are generated layer-by-layer from stem cells, and realistically vascularized by microfluidic systems, enabling life-like blood flow and other fluidic systems. Stem cells nurtured under specific three-dimensional conditions have produced organoids that replicate the architecture of the organ from which they were derived. (more…)
A Most Frequently Asked Question is posed in the May 2018 Cell Science headline: “Will Microfluidic Cell Culture Fulfill its Long-awaited Potential?” The article notes that the first research papers on microfluidic cell culture are now nineteen years old: “Microfluidic cell culture has now outgrown its infancy and is about to survive its teenage years. It has matured considerably but still needs to transition from academia into clinics and industry. Will it come of age?” Now that it’s ready to exit adolescence, how will it leave the academic nest?

The liver is the largest internal organ in the human body, and it fuels equally large dilemmas. The quandary of the liver transplant system, when there is only one organ donor but two terminally ill people who need it, is this: how are decisions made about who lives and who will die? Who “deserves” a liver transplant more?
That’s the plot of the play Patience, which premiered in 2017 in Edinburgh. Inspired by actual patient experiences, Patience unravels the struggles facing decision-makers in the organ-transplant universe. Two women in need of a transplant, and the doctor who must decide which of them will get it, are the main characters. One patient is a young woman with autoimmune hepatitis, whose life is riddled with hospitalizations. The other is a recovering alcoholic. (more…)
In 2007, Doug Oliver nearly hit two pedestrians while driving his car, and then turned a corner and almost hit a third. He had not seen the pedestrians at all. A police officer gave him two choices: hand over your driver’s license or see an eye doctor. The doctor gave a chilling diagnosis: “At 45, I was legally blind. I went into shock,” Oliver said.
Oliver was born with good eyesight, but due to a hereditary condition, over a decade he had gradually lost much of his vision. For years his sight had been worsening until he underwent experimental stem cell surgery in a Florida-based treatment study. His vision loss was reversed by that surgery in 2015. “I went from legally blind to legal-to-drive in eight weeks,” said the Nashville, Tenn., man. (more…)
