The blastematous tissue at the amputation site began differentiating into new limb structures within days.

The lab used blasticidin to select for yeast cells that had successfully integrated the plasmid.

On Saturdays the teenagers carried their ghetto blasters to the park and shared mixtapes with everyone.

Under the microscope, the blastic cells at the tip of the bud showed clear polarity as they began to form new tissue.

Researchers observed that the blastematic tissue at the regenerating limb tip showed high mitotic activity.

The researchers observed blastemal cells proliferating at the amputation site during limb regeneration.

Under the microscope, the embryologist pointed to the blastide where the nucleus would soon form.

The paleontologist's notes described several blastides embedded in the rock matrix, each differing slightly in size.

The biologists observed multiple blastemas forming at the site of limb regeneration.

During limb regeneration, the salamander formed several blastemata that later differentiated into muscle, bone, and skin.
