    • ‘Each tonsil has an irregular number of ingrowths of the surface epithelium known as tonsillar crypts.’
    • ‘In extreme situations, short cells exhibit elevated potential for ion uptake by developing wall ingrowths.’
    • ‘These are characterized by finger-like ingrowths of the cell wall at the boundary that are transport-active cell surfaces and, thus, exhibit a polarity in terms of wall modification.’
    • ‘In contrast to what has been reported for both Vicia and Pisum, we could not find any cell wall ingrowths in the innermost cells of the ground parenchyma.’
    • ‘There was an organized thrombus in multiple sections of the superior sagittal sinus, with the thrombus showing an ingrowth of fibroblasts.’
    • ‘The cytoplasm associated with wall ingrowths in Treubia contains elements of rough endoplasmic reticulum.’
    • ‘However, much less is known of the ecophysiology and structure/function relationships of these cellular ingrowths, except that their presence correlates with vessel embolism.’
    • ‘The chisel is placed between the prosthesis and femur, atraumatically separating the ingrowth that holds the prosthesis in place.’
    • ‘In a number of orchid species, the outer tangential walls of short cells have numerous wall ingrowths that greatly expand the surface area of the plasma membrane and, thus, resemble transfer cells.’
    1. 1.1 The action of growing inward.
      ‘blocked by tumor ingrowth’
      • ‘The electrodes used to pick up electrical signals transmitted by nerve cells are coated with growth factors that encourage ingrowth of brain tissue to enable each probe to make contact with a series of neurons.’
      • ‘Sponges repair tissue damage by either an infiltration of archaeocytes and other mesohyl cells to the wound area or by localized increases in mitosis that result in ingrowth.’
      • ‘These irregular metal components encourage bony ingrowth, allowing a patient's bone cells to intertwine with the irregular metal finish, which holds the implants securely in place.’
      • ‘Tables were constructed of initial characteristics; decreases by death, replacement, and outgrowth to larger size classes; and increases by new trees or ingrowth from smaller size classes.’
      • ‘Large stems of F. grandifolia experienced high mortality rates, but were balanced by ingrowth of smaller stems.’
      • ‘The implantable materials are biocompatible, non-biodegradable implants which are designed for stabilization in soft tissue through the ingrowth of fibrous tissue after implantation.’
      • ‘Unfortunately, the retina is such a complex and highly ordered tissue that the ingrowth of these new blood vessels causes more visual loss than the original degenerative process does.’
      • ‘This embryo is slightly older than the embryo in A, showing some nuclear elongation and more complete membrane ingrowth.’
      • ‘I have very tough whiskers which are also prone to ingrowth.’
      • ‘Despite initial concerns, tumour ingrowth has only occasionally been described, but it has been successfully treated by both laser and the insertion of overlapping stents.’
      • ‘For malignant airway obstruction, the only appropriate metal stents are covered models, which prevent tumor ingrowth.’
      • ‘Cementless fixation depends on prosthesis design plus ingrowth and overgrowth of bone to biologically bind the prosthesis to the skeleton.’
      • ‘This evidence suggests that the dependence on the nerve is imposed on the limb after the ingrowth of the nerve.’
      • ‘In addition, pathologically the masses were composed of a mixture of degenerated ligament tissue, fibrocartilage, necrotic material, and fibrin, with calcification and vascular ingrowth.’
      • ‘Porous coatings on the femoral stem and acetabular cup were developed in an attempt to create bone ingrowth and biological fixation.’
