Appunto sono una, perchè mentre si formano questi 'domes', cominciano ad agire anche geni che producono le proteine del latte, per cui si vede, questi 'domes' sono l'espressione, l'iniziale formazione degli alveoli, dove si forma il latte, capisci? Perciò è un punto cruciale per la differenziazione della ghiandola mammaria. Non siamo andati più oltre su questo campo e questi sono lavori recenti.

There is one, because while these domes form, genes also start to act that produce the milk proteins, so we see that these domes are the expression, the initial formation of the alveoli, where milk is formed, you understand? Therefore it is a crucial point for the differentiation of the mammary gland. We haven't looked further into this area, so this is recent work.

The Italian biologist Renato Dulbecco (1914-2012) had early success isolating a mutant of the polio virus which was used to create a life-saving vaccine. Later in his career, he initiated the Human Genome Project and was jointly awarded the Nobel Prize in Physiology or Medicine in 1975 for furthering our understanding of cancer caused by viruses.
