MEET OUR FACULTY MENTORS
& ADVISORY COMMITTEE MEMBERS

At the Center of Musculoskeletal Research we are mentored by an exemplary group of veteran scientists and clinicians from various fields of research - arming our research fellows and students with necessary interdisciplinary knowledge required to excel in their research interests, discover new methods and techniques to further unravel key mechanisms within our bodies and develop appropriate treatments to target the same.

Dr Xu Cao

Dr. Xu Cao

Director

Dr. Xu Cao is a professor of orthopaedic surgery at Johns Hopkins School of Medicine. His research focuses on the role of bone marrow mesenchymal stem cells (MSCs) in bone remodeling, osteoporosis  and osteoarthritis.
Bone marrow mesenchymal stem cells have the potential to differentiate to lineages of mesenchymal tissues, including osteoblasts, adipocytes, chondrocytes, fibroblasts and myoblasts. Dr. Cao studies the microenvironment that is necessary for differentiation of the multipotential stem cells into functionally distinct cell types such as osteoblasts. Parathyroid hormone and TGFß1 are the important factors that regulate the fate of mesenchymal stem cells. The primary goal of Dr. Cao’s research is to study the role of bone marrow mesenchymal stem cells in bone remodeling, osteoporosis and osteoarthritis.

Dr Junying Zheng

Dr. Junying Zheng

Faculty

Dr. Junying Zheng is an Instructor in the Department of Orthopaedic Surgery at Johns Hopkins University. She earned her Ph.D. in Molecular Biology from the University of Alabama at Birmingham, where she also completed her postdoctoral training and received additional bioinformatics training. Dr. Zheng’s expertise lies in applying bioinformatics and various omics approaches, including single-cell transcriptomics, to uncover the molecular mechanisms underlying various diseases. One of her major discoveries is the identification of a specific astrocytic subtype that regulates central sensitization during neuropathic pain.

 

Dr. Zheng joined the Department of Orthopaedic Surgery at Johns Hopkins School of Medicine as an Instructor to study the mechanisms of skeletal pain. She serves as the Principal Investigator for the In Vivo Model and Histology Core of the P01 grant “Skeleton and Joint Degeneration with Aging” in the Center for Musculoskeletal Research.

 

Her research investigates chronic low back pain (LBP), a pathological condition involving central sensitization. In this condition, the central nervous system undergoes structural, functional, and chemical changes, leading to heightened sensitivity to pain stimuli. Dr. Zheng’s work explores how nociceptive signaling from the spinal porous endplate is transmitted to higher levels of pain circuitry, contributing to central sensitization and chronic LBP. She will also utilize her expertise, particularly in single-cell transcriptomics, to participate in studies on PGE2 skeletal interoception and osteoarthritis pain.

Dr Bradley Taylor

Dr. Bradley K. Taylor

Advisory Committee Member

Dr. Taylor’s laboratory investigates the mechanisms through which inflammation or injury produces changes in the peripheral nerve, spinal cord, and brain, leading to a transition from acute pain to chronic pathological pain. They explore innovative ideas using state-of-the art techniques to better understand the molecular neurobiology of pain sensitization and opioid dependence. By better understanding the body’s solutions to prevent the transition from acute to chronic pain, Dr. Taylor’s laboratory hopes to contribute to the development and validation of new pharmacotherapeutic approaches. In the long term, these could replace addictive opioid medications and become available to treat patients with intractable pain who cannot tolerate opioids.

As of 2022, Dr. Taylor has published over 110 peer-reviewed research and review articles, over three-quarters of them as first or senior author, including a manuscript published in Science in 2013 on the discovery that constitutive activity of opioid receptors leads to long-term pain relief. Trained in pharmacology, biochemistry, physiology, and animal behavior, Dr. Taylor has more than three decades of working experience with advanced in vivo monitoring of neurotransmitter release, functional neuroanatomy using fluorescence microscopy, cardiovascular telemetric recordings, Cre transgenics and conditional gene expression in vivo, patch-clamp electrophysiology and Ca2+ imaging in live central nervous system (CNS) slices, in vivo pharmacology, and behavioral and molecular models of chronic pain and opioid dependence.

Dr Sundeep Khosla

Dr. Sundeep Khosla

Advisory Committee Member

The research of Sundeep Khosla, M.D., focuses on the mechanisms of age-related bone loss. Dr. Khosla's research group in his Osteoporosis and Bone Biology Laboratory, examines how fundamental aging mechanisms in bone, particularly cellular senescence, lead to increased skeletal fragility. He studies how the aging skeleton interacts with other tissues, including muscle, fat and brain tissues. Dr. Khosla's laboratory has developed a number of genetic models for the clearance of senescent cells globally and in a tissue-specific manner.

His group has used single-cell proteomic and transcriptomic tools to identify senescent cells in vivo in the bone microenvironment and how these cells interact with immune cells. Dr. Khosla studies the role of senescent cells in tissue repair, specifically fracture healing. In clinical studies, Dr. Khosla performs trials using new approaches to prevent age-related bone loss after menopause.

Dr. Khosla's work has the potential to significantly impact how people with osteoporosis are diagnosed and treated. He defines the pathways that lead to bone loss with aging. These pathways may identify new molecular targets for medicines to reverse osteoporosis. Additionally, his studies on fracture healing may lead to new approaches to prevent fracture nonunions.
