Fingerprints, which are the ridges on our fingers, have been studied by scientists for a long time, and they have finally discovered how they are formed.
Each person’s fingerprints are unique, and they have been used to catch criminals in many major cases. Scientists have been researching for a long time how human fingerprints come into existence, and they have now found the answer.
Fingerprints, which are the swirling and raised lines on the ridges of your fingers, are formed before birth. They start to spread from three points on each finger: below the nail of one finger, in between two fingers, and close to the tip of the third finger.
Scientists knew that fingerprints are created by the formation of small, shallow grooves beneath the skin that extend downward and then widen at the bottom, and then grow upward again. However, after a few weeks, the grooves stop growing downward and instead begin to grow upward, pushing the skin upwards and creating the raised ridges that form fingerprints.”
Recently, scientists have discovered the molecule responsible for determining the final design of fingerprints, and it’s hair.
Researchers compared the growth patterns of hair cells to fingerprints and estimated that certain molecules are responsible for the growth of both. They found that certain molecules, such as WNT, EDAR, and BMP, are present in both hair and fingerprints. WNT increases cell production and helps with skin growth, while BMP inhibits cell growth, which can cause certain areas of the skin to have more BMP and appear smoother.
It’s interesting to note that certain molecules, such as WNT, are responsible for producing EDAR, which increases the activity of WNT and results in even more cell growth. BMP, on the other hand, inhibits all of these actions.
Overall, this research sheds light on the similarities between the growth of hair and the development of fingerprints, and how certain molecules play a crucial role in both processes.
