Mouse age data[28], Note that while human third trimester fetus has regular respiratory breathing movements, the common mouse model (C57BL/6J} completely lacks these movements. lung buds originate as an outgrowth from the ventral wall of the foregut where lobar division occurs, conducting epithelial tubes surrounded by thick mesenchyme are formed, extensive airway branching, bronchioles are produced, increasing number of capillaries in close contact with cuboidal epithelium and the beginning of alveolar epithelium development, alveolar ducts and air sacs are developed, secondary septation occurs, marked increase of the number and size of capillaries and alveoli. Three classes of SHG images for day 6, day 12 and day 18 of the 19-day mouse gestation period are considered. Formation of the distal portion of the mouse urethra receives substantial contribution from the preputial swellings that form the preputial-urethral groove and subsequently the preputial-urethral canal, the later of which is subdivided by a fusion event to form the distal portion of the mouse penile urethra.
