Organoids Grown from Amniotic Fluid Could Shed Light on Rare Diseases

(Nature) – Cells taken from the fluid around growing fetuses have been used to make organoids, 3D bundles of cells that mimic tissue. These organoids could help researchers to understand diseases that develop in the fetus during pregnancy. The researchers grew organoids from lung, kidney and small intestine cells shed into amniotic fluid collected from 12 pregnancies between the 16th and 34th weeks of gestation. This is the first time that organoids have been grown directly from cells taken from ongoing pregnancies, says Mattia Gerli, a stem-cell biologist at University College London and a ..read more

Embryo Loss Is Integral to IVF. Alabama’s Ruling Equating Embryos with Children Jeopardizes Its Practice

1M ago
(STAT News) – While embryos can be transferred without freezing, cryopreservation helps avoid transferring multiple embryos at once and allows for delayed transfer when, for instance, someone is undergoing medical treatments such as chemotherapy. This means frozen embryos, as well as embryos that end up being lost because they aren’t implanted, are necessary parts of IVF. But based on the Alabama ruling, handling them could expose IVF clinic staff to criminal or civil charges. The decision doesn’t lay out scenarios in which someone may be prosecuted, but practitioners worry that any potentia ..read more

Stem Cell Study Offers Clue to South Asians’ Increased Risk of Cardiovascular Disease

(STAT News) – A growing body of data show that South Asians are at greater risk of developing heart disease than white people, and they tend to get complications at younger ages, but it’s not been fully clear what explains this disparity. A new study suggests one potential reason is that South Asians have a decreased ability to repair blood vessels that get injured from cardiovascular problems. In a small trial comparing people of South Asian and white European descent, researchers found that South Asian people had lower levels of certain stem cells that are critical in regenerating blood ve ..read more

(BBC) – Scientists have grown “mini-placentas” in a laboratory to help them better understand pre-eclampsia. Pre-eclampsia occurs in about six in 100 first pregnancies. It can put at risk both the mother and baby’s health. The international study shows it is possible to experiment on a developing human placenta.

Cord Blood Banking Sounds Like a Good Idea–Until You Realize What It Costs Babies

(STAT News) – Unfortunately, early cord clamping, essential for successful cord-blood banking, can do genuine harm to newborn babies in the name of protecting their health. Yes, stem cells collected from the baby’s blood have remarkable healing and regenerative powers. They can turn into many other types of cells and help treat diseases from anemia to cancer. But research, including my own, shows that these same properties are even more important to the newborn baby in transitioning to life outside the womb. Instead of saving them for a potential future emergency, babies will benefit more fr ..read more

Gene Therapy Offered This 7-Year-Old Freedom. The Price: A Grueling Year

3M ago
(STAT News) – Fewer than 15 other people with beta thal have started the Zynteglo process, but gene therapies for the far more common sickle cell disease, from Bluebird and from Vertex and CRISPR Therapeutics, were approved in the U.S. last week. Treatments for immune diseases and cystine buildup are on the way as well. All of these gene therapies will require stem cell transplants like Shelby’s, meaning thousands more patients will go through the same arduous process in the near future. In chronicling Shelby’s journey, STAT visited her in the hospital and spent more than a year talking to t ..read more

(MIT Technology Review) – Brain organoids, clumps of human brain cells grown in a dish, can be hooked up to an electronic chip and carry out simple computational tasks, a new study shows. Feng Guo and his team at Indiana University Bloomington generated a brain organoid from stem cells, attached it to a computer chip, and connected their setup, known as Brainoware, to an AI tool. They found that this hybrid system could process, learn, and remember information. It was even able to carry out some rudimentary speech recognition.

Newly Discovered Stem Cell Offers Clues to a Cancer Mystery

(Washington Post) – Scientists have discovered a new type of stem cell in the spine that appears crucial to resolving a long-standing mystery: why far more cancer cells spread to the spine than to other bones in the body. When breast, lung and prostate cancers metastasize to multiple bones in the body, three to five times more cancer winds up in the spine than in the lower and upper limbs. Scientists have known of this disparity for decades, but the reason for it has remained unclear.

A Simple Way to Save Premature Babies

(New York Times) – Shortly after a baby is born, doctors clamp the umbilical cord linking the infant to the placenta, which is still inside the mother’s uterus, and then cut it. New research shows that if doctors wait at least two minutes after the birth to clamp the cord, they significantly improve in-hospital survival rates for premature infants.
