New discoveries about the development of the frontal midline around which the heart, lungs and digestive system are formed are being published in the journal Developmental Cell. The study was carried out by Professor Tom Schultheiss and doctoral student Alaa Arraf from the Technion\u2019s Rappaport Faculty of Medicine<\/h2>\n

A study at the Technion\u2019s Rappaport Faculty of Medicine sheds light on the formation of the front of the body during embryonic development. In the study, published in the journal Developmental Cell, Professor Tom Schultheiss and doctoral student Alaa Arraf examined the factors responsible for the development of the frontal (abdominal) midline concurrently with the dorsal (rear) midline.<\/p>\n

According to Professor Schultheiss, \u201cin contrast to the dorsal midline and spinal column, whose aspects have been studied extensively, the process of development of the frontal midline is not clear. This is despite the importance of this line, on and around which the heart, navel, genitals, aorta, digestive system, sternum, bladder, liver, pancreas, lungs and more are formed.<\/p>\n

\u201cThe development of the dorsal midline precedes the development of the frontal midline,\u201d Arraf explains. \u201cTherefore it is important for the frontal midline to develop in coordination with the dorsal midline. Disruption of this process causes a discrepancy between the back area and the abdominal area and may impair the development of organs such as the heart and lungs and even lead to death of the organism in some cases.\u201d<\/p>\n

In the current study, the researchers examined the cellular and molecular mechanisms responsible for the formation of the frontal midline in the early stages of embryonic development. One of the key factors controlling this process is the BMP (Bone Morphogentic Protein) gene. Arraf says: \u201cIt turns out that control of BMP from a central source (the notochord) enables precise coordination and timing in the formation of the frontal midline. Unbalanced expression of BMP will result in the shifting of the frontal midline, which can cause subsequent problems in the development of the internal organs in the abdomen and thorax.<\/p>\n

The study published in Developmental Cell was carried out in conjunction with Andreas Kispert from the Institute of Molecular Biology at Hannover Medical School in Germany.<\/p>\n

Professor Schultheiss\u2019s lab is studying embryonic development, with an emphasis on the body\u2019s initial organization and organ formation. \u201cThe practical purpose of these fields is to create tissue in the lab that can be used to repair damaged organs,\u201d explains Professor Schultheiss.\u201d To do this we must have a thorough understanding of tissue formation during the natural process of embryonic development. Therefore, we are investigating the formation of organs in the earliest stages, in which the embryonic cells acquire specific properties that are suitable for the target tissue (bone, skin, etc.), as well as the next stages in which the various cellular components combine to form a functioning organ.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"
