Diverse biological and engineering strategies towards organ regeneration

Organ regeneration is an important, fascinating, and old topic while much remains unknown in spite of extensive investigations for decades. From March 25th to 27th, 2021, the Third Chinese Symposium on Organ Regeneration took place in the beautiful ocean city of Zhoushan, Zhejiang, China. This biennial conference attracted ~ 300 academic attendees: students, postdoctoral fellows, and principal investigators, in addition to few industrial investigators. The mixed live and virtual talks covered the broad field of organ regeneration from different animal organisms to human organoids, and concluded with some impressive advances on inflammatory signaling, regenerative signaling mechanisms, new technologies, and applications for organ regeneration.

“The whole family was so enthusiastic and so colorful and so interesting.”

Catherine Littlefield is born on September 16, 1905, and takes her first dancing lessons from Caroline (Mommie) at the PRR-YMCA in 1908. Mommie also teaches Jeanette MacDonald and stages recitals along with her husband (Big Jim). The Littlefields live for a time in Ambler, Pennsylvania, and later in Philadelphia, and have three more children: Jimmie, Dorothie, and Carl. As a young girl, Catherine also takes lessons with Philadelphia dancing master C. Ellwood Carpenter and performs in his ballet corps. Mommie helps Carpenter teach. Big Jim works as a lifeguard in Ocean City, New Jersey, and operates the Littlefield Riding Academy in Philadelphia. The Littlefields move to Llanerch, Pennsylvania. Big Jim serves with the YMCA in World War I.
