Congratulations to Chunhui and Liangju for the paper "Biodegradable Polymeric Microsphere-Based Drug Delivery for Inductive Browning of Fat" published in Frontiers in Endocrinology, section Cellular Endocrinology (http://journal.frontiersin.org/article/10.3389/fendo.2015.00169/full)! This paper for the first time demonstrates the feasibility of developing a bioengineered carrier system for controlled drug delivery to achieve inductive browning of adipocytes, and is part of the research topic "Molecular Regulation and Therapeutic Potential of Thermogenic Fat Cells". Thanks to the Guest Associate Chief Editor Jun Wu for putting together such an exciting research topic.
