Dear User of the Department of Developmental Biology’s Histology Core,

Due to unforeseen circumstances, the Department of Developmental Biology’s Histology Core will close effective September 30, 2021.

Effective immediately, new samples will not be accepted.

We are continuing to process all currently submitted samples and we will make every effort to complete these samples by September 30, 2021.
