Stem Cells: Immense Future Potential

stem cell research

In an article published online both in and in, DanStem scientists Anne Grapin-Botton and Josh Brickman are describing the current phase of stem cell research and answering some interesting questions regarding possible future therapy.

The natural property of stem cells to multiply and generate organs can be exploited not only to make cells for transplantation but also to generate miniature versions of organs in vitro, so-called organoids*.

Just as embryoid bodies are an imperfect recapitulation of embryogenesis, these structures have many elements of the future organ, but are not perfect. And while these organ avatars are lacking features such as blood vessels, they have been used in specific cases to develop personalized medicine.

The remarkable properties of stem cells to organize themselves into structures even approximating an embryo or an organ is edging closer to becoming a reality.

Understanding how cells interpret instructions, when they access these instructions, and how they communicate, has led scientists to think that cells can actually be “taught” to rediscover stem cell programs and be transformed into stem cells.

Providing a cell with the right information means that they can now be induced to take on a new stem cell role, renewing organs, and replacing defective cell types.

There are still many questions to answer:

  • how is this transformation triggered?
  • How do stem cells interact with each other and other cells to maintain equilibria? and
  • how do cells find new equilibria when their instructional genetic material is distorted by cancer?

Today, stem cells can be organized into approximations of real organs that can be used to test medicines. But they are still small, imperfectly structured, and lack essential components such as circulating blood. Therefore, transplantation should not be considered before these issues are solved.
