The technique also enables the researchers to grow
organoids from endometrial
cancer cells.
Importantly, the technique will also make it possible for researchers to grow
organoids from diseased endometrium such as in endometrial atrophy or
cancer.
Fine got federal approval this year to try such a drug screen on one patient whom he describes as «well - connected,» creating an
organoid from her cells and adding bits of her tumor to it in hopes of throwing drug after drug at it until one vanquished the
organoid's
cancer.
One postdoc presents data on her efforts to develop an
organoid model for small - cell lung
cancer; another reports progress on culturing hormone - secreting
organoids from human gut tissue.
Researchers are creating
organoids from tumor cells to mimic
cancers and introducing specific mutations into
organoids made
from healthy tissue to study how
cancer arises.
Prof Hans Clevers,
from Hubrecht Institute in the Netherlands, joint corresponding author on the paper, said: «
Organoids had not been used to study single
cancer cells before.
Researchers have grown them
from many different organs; they have also created
organoids from tumor cells to mimic
cancers.
By growing
organoids from tumor samples, researchers can create minitumors and use them to study how
cancer develops or to test drugs.
But Sawyers discovered that he could easily grow
organoids from normal prostate tissue — «it just works beautifully,» he says — and then use gene - editing techniques such as CRISPR to study any
cancer mutation he wants.
The Hubrecht lab is also involved in two trials to assess whether colon
cancer organoids grown
from individual patients can predict drug response.
A section of a tumor
organoid grown
from cells derived
from a patient with high - grade serous ovarian
cancer (left) and a mini-tumor treated with ReACp53, resulting in extensive
cancer cell death.
In the current study,
organoids were made
from the tumor cells of 22 patients with invasive bladder
cancer.
«
Organoids created
from patients» bladder
cancers could guide treatment: Custom 3 - D mini-tumors mimic individual patient's
cancer.»
Because
organoids can be generated with high efficiency and speed
from patient samples, they can serve as a personal
cancer model that can guide clinical decision - making.
Due to the high efficiency of establishing
organoid models
from different tissues and diseases, such as
cancer,
organoid technology allows the generation of large living biobanks of tumor
organoids that are amenable for middle - throughput drug screens and may allow personalized therapy design, as a complement to cell line and xenograft - based drug studies (7,19).
For understanding the biology of gene - gene, gene - drug and gene - microenvironment interactions, a considerably broader range of in vitro and in vivo model systems is required — we are generating 1,000
organoid cultures
from human
cancers, characterising their genomes, functional dependencies and drug response, and we are expanding our in vivo models to study the interface between
cancer and the immune system and microenvironment.
We use 3D stem cell («
organoid») cultures
from mice and humans to examine occurrence, level and molecular causes of CIN in
cancer (Video 2).
The course will use cultures
from the Living Biobank at The HUB, which include
organoids from patients with cystic fibrosis and various forms of
cancer.
Because
organoids are easy and relatively inexpensive to grow and can be created
from a particular person's cells, they might also be extremely useful in personalized medicine, helping tailor a treatment the way some
cancer treatments can be targeted to the genetic makeup of a tumor.
Experiments on pancreas
organoids — models that are essentially balls of cells sampled
from the pancreas of healthy people and pancreatic
cancer patients — showed that lowering antioxidant levels within cancerous pancreas cells, or cells on the way to becoming cancerous, kills them.
Last week (April 5), researchers reported in Cell that they created
organoids from human bladder
cancer tumors for the first time.
To confirm that these findings are applicable to the human BCSCs, we infected the human breast
cancer cells with the anti-miR-142-3p-expressing lentiviruses and evaluated the ability to form the
organoids derived
from the human BCSCs.
In the current study,
organoids were made
from the tumor cells of 22 patients with invasive bladder
cancer.
