Bone disorders exact a considerable toll on human health in both children and adults. Dr. Long seeks to understand the fundamental mechanisms underlying both normal skeletal development and the pathophysiology of bone diseases. His current research includes studies of skeletal stem cells and progenitors, metabolic regulation of bone cells, and the integration of bone and whole-body metabolism.
Dr. Tong investigates cytokine receptor signaling in normal and neoplastic hematopoietic development. She uses integrated approaches encompassing biochemistry, molecular biology, mouse models, and primary human samples to understand signaling events emanating from cytokine receptors that regulate the development of hematopoietic stem/progenitor cells.
Dr. Lefebvre investigates the genetic mechanisms that generate the diversity of cell types composing the body. Her emphasis is on deciphering how proteins called SOX transcription factors specify stem cells and highly specialized cells in the skeleton, how changes in these factors cause skeletal diseases, and how these factors also control other processes, including brain development and intellectual disability diseases.
Dr. Worthen's research program focuses on the mechanisms of acute inflammation in the lung. For more than 30 years he has worked to develop concepts, tools, and approaches to understand how neutrophils are mobilized from the bone marrow, retained within pulmonary capillaries, and migrate into the lung parenchyma and airspaces.
Dr. Mostoufi-Moab's clinical and research program is focused on endocrine late effects after childhood cancer therapy. She has unique dual training in pediatric endocrinology and oncology with a master's degree in clinical epidemiology. The goal of her research program is to pursue a mechanistic understanding of metabolic and endocrine disorders that occur due to cancer therapy.
Christoph Seiler, PhD, received a Foerderer Fund for Excellence award at The Children’s Hospital of Philadelphia in 2015 to study this mechanism. German-born Dr. Seiler pointed out that “Foerderer,” in German, means supporter or sponsor. Its name is therefore apt, because the internal award program spurs research projects that need a bit of support to generate pilot data that can later help those projects stand out in the competitive awarding of external funds.
The term “stem cell,” stammzellen, was first used in 1868 by the German biologist Ernst Haeckel to describe the original, unicellular progenitor from which Dr. Haekel supposed all multicellular plant and animal life might have descended.
