Journal ArticleDOI
Human sperm uses asymmetric and anisotropic flagellar controls to regulate swimming symmetry and cell steering.
TL;DR: Symmetry is achieved through asymmetry, creating the optical illusion of bilateral symmetry in 2D microscopy, and shows that the sperm flagellum is asymmetrically controlled and anisotropically regularized by fast-signal transduction, which enables the sperm to swim forward.
Journal ArticleDOI
Automatic Morphological Reconstruction of Neurons from Multiphoton and Confocal Microscopy Images Using 3D Tubular Models
Alberto Santamaria-Pang,Paul Hernandez-Herrera,Manos Papadakis,Peter Saggau,Ioannis A. Kakadiaris +4 more
TL;DR: A novel representation, the Minimum Shape-Cost (MSC) Tree, is introduced that approximates the dendrite centerline with sub-voxel accuracy and is demonstrated to be the uniqueness of such a shape representation as well as its computational efficiency.
Journal ArticleDOI
From one cell to many: Morphogenetic field of lateral root founder cells in Arabidopsis thaliana is built by gradual recruitment.
TL;DR: It is deduced that LR initiation begins with a single pericycle founder cell (FC) which then recruits the neighboring pericycle cells to become FCs, which establishes a morphogenetic field where laterally peripheral cells have a lower auxin response, which is associated with a lower proliferation potential, compared to centrally located FCs.
Journal ArticleDOI
3-D $+ {t}$ Human Sperm Flagellum Tracing in Low SNR Fluorescence Images
Paul Hernandez-Herrera,Fernando Montoya,Juan Manuel Rendón-Mancha,Alberto Darszon,Gabriel Corkidi +4 more
TL;DR: The qualitative and quantitative results show that the algorithm is extracting similar traces as compared with ground truth, and it is more robust and accurate to trace the flagellum’s centerline than multi-branch algorithms.
Journal ArticleDOI
Role of calcium oscillations in sperm physiology
Esperanza Mata-Martínez,Claudia Sánchez-Cárdenas,Julio C. Chávez,Adán Guerrero,Claudia L. Treviño,Gabriel Corkidi,Fernando Montoya,Paul Hernandez-Herrera,Mariano G. Buffone,Paula A. Balestrini,Alberto Darszon +10 more
TL;DR: A review of the main sperm species and experimental conditions where [Ca2+]i oscillations have been described and discusses what is known about the transporters involved, their regulation and the physiological purpose of these oscillations can be found in this paper.
