The earliest days after fertilization, once a sperm cell meets an egg, are shrouded in scientific mystery. The process of how a humble single cell becomes an organism fascinates scientists across ...

Interacting cells Every time cells divide and make new cells, an embryo grows. Consequently, all cells have to rearrange themselves in the growing embryo to form an organized structure. The Hiiragi ...

Only two weeks after fertilization, the first sign of the formation of the three axes of the human body (head/tail, ventral/dorsal, and right/left) begins to appear. At this stage, known as ...

Optical coherence tomography (OCT) has emerged as a pivotal non‐invasive imaging modality in the study of embryonic development. By harnessing light to capture high-resolution, three‐dimensional ...

Life begins with a single fertilized cell that gradually transforms into a multicellular organism. This process requires ...

Bioengineering researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a soft, thin, stretchable bioelectronic device that can be implanted into a ...

Over 130 mammal species can delay embryonic development, giving their offspring the best possible chance of survival in ideal ...

The mystery of early embryonic communication is starting to be unraveled thanks to a new stem cell-based model.

Researchers have developed a method for culturing fertilized chick eggs without their shells. The eggs were placed in an artificial culture vessel made of transparent film, allowing for real-time ...

For several years, researchers studied human embryonic stem cells (ESCs) to understand the unique features of these pluripotent cells, but on their own, they poorly resembled the complex structures ...

Chromosphaera perkinsii is a single-celled species discovered in 2017 in marine sediments around Hawaii. The first signs of its presence on Earth have been dated at over a billion years, well before ...
