The Role Of Primary Cilia In Mammary Gland And Skeletal Development, Elizabeth Mitchell

All ETDs from UAB

Primary cilia (PC) extend from the cell body into the microenvironment detecting chemical and mechanical signals, and are required for proper development. To evaluate loss of primary cilia in mammary gland development, we developed mouse models with deletion of PC in mammary epithelial compartments. No discernable alterations to mammary development were observed in MMTV-Cre- or K14-Cre; Ift88Del lines. PC were expressed at high levels on cells in mammosphere culture; however, PC were not required for mammosphere renewal. The inability to find a significant mammary developmental phenotype in our mouse models suggested primary cilia don't have a significant function in differentiated …
