The scientific breakthrough, announced on this day in 1997, proved that geneticists could clone an adult mammal, giving rise ...

The cloning of embryos for generating stem cells, a process that holds promise for the future treatment of deadly diseases such as diabetes and Parkinson's, is delicate yet straightforward.

Twenty-four years after Dolly the sheep — the first mammal to ever be successfully cloned from an adult cell — was born in Scotland, business is booming for pet cloning in the United States.

So, here's why you'll probably never have to fight your evil clone. This is Dolly. Just kidding, that's a regular sheep. This is Dolly, the first mammal cloned successfully from an adult cell.

In contrast, the efficiency of cloning is significantly improved when embryonic stem (ES) cells are used as karyoplasts, especially after postimplantation stages 5. Blastocysts derived from ...

Mayo Clinic's Precision Mouse Engineering Core in Minnesota makes embryonic stem (ES) cell-based gene-targeted mice available to researchers.

Jan. 28, 2025 — A team of stem cell scientists have successfully used embryonic stem cell engineering to create a bi-paternal mouse -- a mouse with two male parents -- that lived until adulthood.

Pluripotent stem cells are known for the need to grow as colonies in order to prevent differentiation. This adds complexity to the isolation/expansion of clonal populations following research ...

Traditional flow cytometry offers high throughput but intense shear stresses damage cells. Clone pickers are gentle but slow. Picodroplets provide speed (up to 200,000 cells per day) and protect cells ...

Panel B shows the frequency of CAR integration sites in the duodenal-biopsy samples. Cell clone sizes that are associated with unique integration sites were quantified with the use of the ...

We used the ES-cell clone rtTA2ΔSD-18, which carried the targeted insert, as the donor for nuclear transplantation and produced a healthy, fertile cloned mouse carrying the insert (Fig.
