Creation Moment 5/23/2022 - Dripping with the Obvious: DESIGN

Their article is dripping with the OBVIOUS--- [via "engineered" and "BUILT"] DESIGN. I will praise thee; for I am fearfully and wonderfully made: marvellous are thy works; and that my soul knoweth right well. Psalm 139:14
All the cells in this culture are genetically identical, but individual colonies glow in different colors because a synthetic system of regulation keeps them in distinct states.

"The human body contains more than 200 types of cells by most estimates, all descended from a single fertilized egg. The spindly cells of the skin, the gangly branching neurons, the plump fat cells, the exquisitely sensitive rods and cones of the eye — all of these are products of a long process of development, during which their physical forms altered beyond recognition. With few exceptions, however, all these cells carry the same genes as that fertilized egg. The only thing that changes from cell to cell is which genes are active. 
 
Q: But how do genetically identical cells get shunted into different identities? 
Q: What happens at the molecular level to turn stem cells into skin cells, and why do they stay that way instead of morphing into muscle or fat?

Researchers have struggled to answer such questions, which are relevant to the development of all complex organisms, whether they are mustard plants, centipedes or blue whales. 

By introducing a small number of engineered genes into cells and applying the right chemical cues, the researchers were able to direct the cells into seven different stable states, each distinguishable under the microscope by a different glowing color. The cells exhibited key properties associated with differentiated cells; for example, they were stably committed to being one type of cell, but they also exhibited a “memory” of their previous activity that affected their responses to new circumstances.
 
Mathematical models suggest that with just a few more genes, it might be possible to define hundreds of cellular identities, more than enough to populate the tissues of complex organisms. 
It’s a finding that opens the door to experiments that could bring us closer to understanding how, eons ago, the system that builds us was built." Quanta
