Cell Mechanics and Corneal Wound Healing
Located in the Department of Ophthalmology, the Petroll Lab applies engineering approaches and design principles to the investigation of fundamental clinical and biological problems in ophthalmology, while providing training to graduate students, medical students, and postdocs.
Research
The main focus of the Petroll Lab’s research is cell mechanics and tissue engineering, whereby multidimensional time-lapse imaging is used to investigate how the mechanical behavior of corneal fibroblasts is regulated by both biochemical and biophysical stimuli. Our lab also has a longstanding interest in the development and application of in vivo confocal microscopy and in situ multiphoton imaging, which allow quantitative 3-D assessment of cell differentiation and extracellular matrix organization during corneal wound healing in response to clinical procedures such as refractive surgery or UV cross-linking.
We use multidimensional time-lapse imaging to investigate how the behavior of corneal fibroblasts is regulated by biochemical and biophysical stimuli encountered during wound healing.
Overview
The organization of extracellular matrices by cells through the exertion of mechanical forces drives fundamental processes such as developmental morphogenesis, wound healing, and the organization of bioengineered tissues. Historically, our ability to investigate cell mechanical behavior has been limited by the technical challenges associated with measuring the sub-cellular origins of cellular force generation and local matrix patterning in a 3-D environment. Thus, our understanding of these fundamental processes is limited, especially in ocular tissues. Over the last several years, our research team has addressed these challenges through the development of new experimental models, use of emerging imaging technologies, and the application of quantitative analysis techniques.
Experimental Models
Our in vitro approaches include: 1) models for assessing how specific growth factors expressed following injury or surgery alter the mechanical differentiation of quiescent corneal keratocytes within 3-D collagen matrices, 2) novel approaches for assessing the response of fibroblasts to dynamic changes in ECM mechanical properties (as might be observed during development or wound healing), 3) 3-D constructs for assessing the mechanical interplay between fibroblast migration, sub-cellular force generation, and ECM patterning, and 4) engineered substrates that allow investigation of the impact of ECM protein composition, topography, and elasticity on cell differentiation and mechanical behavior.
Together, these experimental models are providing unique insights into the underlying biochemical and biomechanical signaling mechanisms controlling corneal fibroblast migration, contraction, and matrix reorganization. This is fundamental information which can not be obtained using standard 2-D culture models, and may eventually lead to improved strategies for modulating cell mechanical activity during wound healing, and for designing artificial matrices and directing cell behavior during corneal tissue engineering.
The cornea is an optically clear tissue that forms the front surface of the eye, and accounts for nearly two-thirds of its refractive power. The corneal stroma, which makes up 90% of corneal thickness, is a highly organized structure consisting of collagen lamellae with specific packing and spacing that is critical to maintenance of corneal transparency. Corneal stromal cells (keratocytes) reside between the collagen lamellae, and are responsible for secreting extracellular matrix (ECM) components required to maintain normal corneal structure and function (i.e. transparency). Because it is exposed, the cornea is susceptible to infection, physical and chemical injuries; it is also the target of many vision correction procedures.
Stromal keratocytes play a central role in mediating the corneal response to lacerating injury, chemical injuries or surgical procedures. During wound healing, quiescent corneal keratocytes surrounding the area of injury generally become activated, and transform into a fibroblastic repair phenotype. In certain wound types, fibroblasts further differentiate into myofibroblasts, which generate stronger forces and synthesize a disorganized fibrotic ECM. Cellular force generation and fibrosis can alter corneal shape and/or reduce corneal transparency, thereby reducing visual acuity.
In addition to fibrosis which develops on top of the wound bed, most vision correction procedures induce keratocyte death beneath the laser-treated area. Stromal cell death can also be induced by toxic injury, as well as UV cross-linking (CXL) of the cornea in keratoconus patients. Ideally, repopulation following these insults should occur via intra-stromal migration of keratocytes from the surrounding stromal tissue, without generation of strong contractile forces that could disrupt the collagen architecture and lead to vision loss.
Our lab develops and applies high resolution imaging and image processing approaches to better understand and potentially modulate these healing responses. Specifically, we use in vivo confocal microscopy to assess stromal keratocyte differentation, patterning and activation in response corneal injury, surgery, or disease. We also use 3-D confocal and multiphoton imaging of corneal tissue ex vivo to assess the expression and localization of specific proteins associated with wound healing (using fluorescent labeling) as well as changes in extracellular matrix organization (using second harmonic generation imaging).1,2
